"it offers a greater sense of occasion and meaning to some" - please define "some" - is that some covered by only the Union Bears, or are you talking about perhaps 10%, or 25% or 50% of the fans who attend Ibrox on match day?
"and generates a more charged and tense atmosphere" - not it doesn't - those things are generated by the sense of occasion, the opposition and what is happening on the pitch. A bigger opposition support also helps charge the atmosphere like we see at away matches.
A decent justification for a standing section would be to remove the UB for a few weeks and see what games were like. - it is not up for debate that the Union Bears generate the a constant and welcome noise at games (apart from the bo66y sands/1ra stuff) - that will be the case whether we are all standing or sitting.
Unsure re numbers, away games and Hampden suggest there is a decent % want to stand at games, it is clear there is an interest in it, to dismiss that there is interest in it is every bit as odd as the idea of those who dismiss those attached to a seat TBH, there is momentum in the want to stand among more than just Rangers fans at the moment, clearly, or sides wouldn't be looking to introduce it.
Factoring in those that stand at away games (it isn't JUST those in BF1 who drive the rest of the support to stand at away games) those in GF1 will often stand during the game, and those who are placed in back rows and last rows at the end of the enclosure take the chance to stand pretty quick during a game rather than be seated, I would suggest there is the interest in it for it to merit a pretty decent discussion TBH.
If fans standing were going to be more vocal (see UB) it evidently would generate a
more charged and tense atmosphere, the general reaction of the club and players to the UB shows this, the club have allowed the UB into the changing room with the trophy, the Captain and ex manager have on more than one occasion openly approached that particular section of the fans and interact with them in a way they don't others in the ground, that is clearly in part thanks to the
more charged atmosphere they create, that could then go hand in hand with what happens on the park, if that then goes on the park it then goes back into the stands.
There is a reason the likes of Bassey windmill his arms when he comes back on the park, or Barisic encourages more support when taking corners.
The UB very rarely make any form of mention about Bobby Sands or the IRA at games, why you have made that reference is quite odd BTW.
If you are of the view an atmosphere can be generated the same when people sit as they do when they stand, why then do people not remain seated when they celebrate or when they join in with songs, the UB are our most vocal support, yet they do this from a standing position not a seated one, same applies with the away support.
It's called the bouncy BTW because it engages people and is interactive, it's not the sitty.
You have asked for reasons re standing sections and the want for it yet seem pretty dismissive of what it can offer TBH, it is kind of clear it's just not for you, but it is though clear is it is for a fair few others.
RE the general split and seating of the ground,
I have been in a position this season where I have been letting others use my ST this season and moving around the ground a few times with match tickets.
It is pretty clear from moving around their are pockets all around the ground who have a far deeper desire and want to stand and sing more often than those around them do
Very often in the stadium pockets will stand, break out to song and it falls flat on it's arse pretty quickly as a result of minimal participation around those who do try and do that, if those fans were placed together (who want to stand and sing) it would clearly drive a more intense atmosphere than the regular burst of the first few words of a song then a sort of..... of f*ck it's just me, no one else has bothered to stand or sing, I will pack it in then as often happens just now.
It would probably increase the experience for those who just aren't that arsed with those who want to stand and sing TBH
The general interaction between UB and those in the SW4 and SW5 is again groups of fans who if all placed in one section would be of benefit.
You really don't seem into the idea fans might just want to stand at our games and the idea that it could be beneficial to atmosphere, despite, as it currently STANDS most of the atmosphere being driven from the section of the stadium that does just that while in other sections of the ground, it is often difficult for it to become charged that often at all TBH
