Why are Polish women against it?
Oh they're just talking gibberish. Each one has it's individual approach to this matter and you won't find a one formula describing attitude of Poles towards gay people. Some are against it, some are not.
Generally women are more tolerant to gays.
Among people who are against it you can find various reason for that:
- general conservatism which is a defence mechanism against changes in world and society (and one of those changes is new approach to the gays' and lesbians' rights)
- religious reasons (but you have to know that people in Poland aren't blindly Catholic and generally don't have any problems with being against church doctrine in many other fields e.g. premarriage sex, contraceptive etc.)
- the reason which gumishu mentioned aboved - men trying to be more manly
- belief that homosexualism is one of sexual disorders, and by accepting it people agrees for libertinism
Personally I think that the first reason is the most popular one. I heard many people having an attitude like that: "I don't mind gays if they don't show their homosexualism in public
Young people tend to be more tolerant for gay people, but of course it depends on the social circles (probably blue collar circles would be less tolerant). Maybe your bf affraids that he would suffer ostrasism if his mates from work will discover that, that they will be less willing to talk with him or keep distance.
Many gay people affraid what would be the reaction of others if they discover their preferences... even though in most cases I know, people already know/suspect that someone is gay even if someone didn't say it openly.
I'm Polish and personally I don't have anything against gay people.
