Well if you're a racist homophobic idiot when drunk ,I guarantee you're exactly that sober tooTo Chris and other English people here: there is a lot of racism in Belgium too. Lot's of people here really hate Lukaku for instance. The fact that our national team took the knee before matches was heavily criticised by right wing political parties t(and in Flanders 45% of the people vote extreme right or a llitle bit less extreme right).
Dome of these extreme right politician supported our adversaries on Twitter during matches (our first goal against Russia had a suspicion of offside - Lukaku was in an off-side position, but the Russain defender touched the ball and so it can never be off-side - one MP even was bashing the ref that he was biased against Russia).
What i want to say: there are jerks in every country, and the problem is that these people generally are loud and clear and so you get the impression that all -Belgians, English, Germans and take any possible nationality- are jerks. There is a silent majority who is not like that....
Concerning (some) English football fans: what concerns me is the drinking that seems to go hand in hand with being a fan. Too much alcohol changes people and seldom in a good way. I have the impression (perhaps wrongly) that English football fans consume too much alcohol. That is something foreign journalists found shockingly sunday.
