I don’t actually think in this day and age 99% of fans could care less. Statistically, if anyone has played football chances are one of the squad was gay or you definitely played against someone who was - you probably didn’t know.
Now the problem here is that even if just 1% of fans are arseholes, that’s a big number of idiots in absolute terms.
The problem with a player coming out as gay is that it’ll be such a big deal, the papers will talk about it for days and the morning TV programmes will go on about it all morning. I doubt I’m on my own here, I really could give a shit what sexuality a player is - look at Hitzlesperger, average player who scored worldies and became a cult hero - would’ve been no different for most of us if he was out at the time.
