Should political flags be allowed

I dont believe it appropriate for Palestinian flags to be on show at Celtic Park on forthcoming match vs A Madrid.

Thats my view and I realise others have different views however what I think is irrelevant vs the bigger picture

We have and have had Israeli players representing Celtic on the world stage…how must they feel?

Will Uefa allow it?
Will Celtic allow it
How will the rest of the world view ys as a club?
England FA stopped it happening in their recent matches

Keep politics out of football a small group of Celtic supporters seem to pick and choose political stands in the name of our club…why?
If Celtic dont prevent it will we get fined again perhaps those showing the flags and sickening banners will have a collection and pay the fines?

Perhaps UEFA will not allow the match to go ahead?
