people shouldn't really hate guys playing as girls in games, it's their fault for getting tricked and it's not like they're cross dressing to make you poor.. its your choice to use money or not and it's not necessary to do that either over a game you can just help the player with ingame loots.
then again the guys that abuse the "girl" characters for advantages are actually a turnoff
i think it's actually not a bad idea for guys to play as girls because not all games have many girls in them and some guys wouldn't want to even imagine being in a game with 1000 to 1 ratio of guys and girls, if half of the guys roleplay as girls then it would turn into a 50/50 ratio, it can sound creepy but i find it cute that guys play as girls.
if anything some of the guys that play girls probably wanted to be a girl irl or a girl trapped in a guys body
it's a game and i think they should have the freedom to be who they want to be as you can't have such freedom in reality.
some girls play as guys to avoid guys flirts or just for plain role play / some could also want a boyfriend ingame since you know how some guys play girls because they are single and want to level their "girlfriend" same could apply for girls on boy characters.
