I am with DB here.
Seems like you want to avoid dealing with homophobic language in the way we have been instructed to.
There is no debate about context when it comes to homophobic, racist and misogynist language.
To the question about languages. I face this every game. I at least have to deal with English and Finnish. Sometimes Swedish, Russian, French, Spanish, Turkish. I have had games with swearing in different combinations of these. I don't know any swear words or insults in some of these languages. You can only play what's put it front of you. This "proves" nothing: I had one south american call a french african "monkey" in Finnish. Easy red card. At the time he and his captain were at pains to point out that there were Hispanics, Finns, Swedes and French Africans on their team (too). Pretty easy reply from me: "all the more reason to take the red card, apologise to your team mates and the other team." And that he did. The guy he called "monkey" had just fouled him, worthy of a yellow - and did look quite apinoid, at least more apinoid than 50% of the population - is that excuse enough to make it OK? No, of course it's not. Its not acceptable in any context.
I don't think you really need a list of homophobic or racist insults do you? You know what they are. You recognise them.
(Misogynist is a trickier and also far more unusual (in my tiny experience)).
I would find absolutely hilarious if someone used "pillow biter" or "shirt lifter" in a game. To be honest I might not be able to hold back laughter. Because my personal context for these phrases is related to memories of father getting me in stitches. However much I find it amusing it's still a red card on the field. My own personal tolerance does not matter here. I am a Liverpool fan. I thought Robbie Fowler's gesture at Le Saux was hilarious because I am an idiot child inside. It's a red card.
Its not the pub, not a club, not the street, not the playground. When you play, you agree to play by the rules (laws). When you ref, you agree to ref by the laws.
Homophobic language/gestures - red card
Racist language/gestures - red card
Misogynist language/gestures - red card
Other swearing/gestures you can make up your own mind, based on the context...
