If you are talking about last night, I didn't hear one FTP inside the ground - by and large since Legia away the travelling Euro support has been exemplary inside the ground(I have only missed Feyenoord away so first hand)
I think alot of the problems are people assuming they know what fans are singing, or just thinking oh it must be sectarian.
Inside a football ground, my own preference is no religious songs at all, no mention of the pope, the vatican, or anything else, we do as a support have a bit to go in that regard (it doesn't help when certain songs like the Cardoso or the Halliday songs are made up) but by and large the rank and file regular attendees have toed the line, alot of the issues arise with your day trippers who won't go to another game for 12 months.
as for the win us some friends
, oh Love me love me, away and fling pish at the moon with that utter nonsense.
