There is a difference between not believing in gender roles, and encouraging your kid to be a homosexual.
What is the difference between not believing in gender roles and encouraging homosexuality?
You can't change sexuality, but a woman can wear pants if she likes and men can wear a dress.
Homosexuality isn't something kids can be pushed to choose from, but is something they're born to be. Children don't need to be made to feel bad for having certain feelings. There are many resources on the topic which can be a great at learning the difference between choice and just being homosexual.
I think it's just a difference of opinion. I don't want other people to force me in something I don't believe. I also don't want my kid to eventually experiment in stuff if I don't show him/her the way.
Well you should just let your kids grow up and try not to pressure them into doing things. If they want to wear something let them. If they turn out to be homosexual be there to support them if a relationship doesn't work out.
