Emphasis mine, but you said both in a connected statement, so I don't see the point in disputing anything about my quotation.
Edit: I see now have you've removed the dispute of my quotation as being inaccurate where you argued you said "particular relation" and not "particular reason" -- no worries, I've made similar mistakes before, so while I'll leave my above words, they don't matter anymore.
As for why Birmingham in particular, I don't see it as some kind of gotcha to say because there is a resident population in Birmingham that would be a likely target of racial/religious abuse by Maccabi fans, i.e., Muslim people, or even just "Arab" appearing people, or people showing Palestine solidarity. Amsterdam and Birmingham are similar in this regard (I lived in Amsterdam for years), in ways other cities may not be. I'm not clued into Stuttgart or the cities hosting other games, so I can't say if populations there are similar or not. Expecting a uniform approach from all cities would be ludicrous -- why mandate ignoring particularities?
I don't think this is a form of intolerance towards Maccabi fans, because the logic is identical to that of the Tel Aviv derby prohibition -- it's about preventing reasonably predictable confrontations that exceed some tolerance level.
