Why should gay adoptions be legal if?

I think a child needs a mom in the household ideally..

It would be discrimination if gay adoption was illegal. Plus, there's a difference between single men choosing not to adopt and gay adoption being illegal.

What's wrong with a single father raising a child/children anyway? Your argument is stupid.

For me, I think having gay parents is going to affect a child's perception on relationships and make the child more likely to be gay. Also I read articles of adults who had two same sex parents and felt like they missed out on having a father or a mother growing up. That is just what I heard. I don't think it should be illegal or anything but it definitely has impact on a kid. I do not know every person who had a two same sex parents or personally have two same sex parents but I still think there are differences between two same sex parents and a mother and father.4

There are single father who still raise their kids properly and might find a mother.

In western liberal society everything is acceptable

What do you mean?

I think the point is that single males (Who are straight) are able to make the choice to adopt. Some may not have the funds to support a child, or the right living conditions, hence they're not accepted, but they're special cases and not the norm. Gay couples cannot be discriminated against simply because they're gay - In fact, having two men to help around the house would, logically, be twice as efficient as having a single male!
As for your point about needing a mom.. I'm not entirely sure. I've gone all of me teenage years without a father, and it hasn't really affected me as much as people would think. I would imagine a mother (Or lack thereof) would have the same effect; particularly one who hasn't got a birthing connection to you, anyway!

Really interesting point, though. I do see where you're coming from, I just think that single males and gay couples are in two separate groups at the moment, which isn't fair on the gay couples.

I don't really think it makes the gay. I know though when gays and lesbians have children they're more likely to be gay but that's more to do with being genetically wired to be gay. I don't think they should not be allowed to have their own kids though. I think that's their business and a personal choice. But them raising other children is more questionable. Maybe not banned but it's the least acceptable possibility for the child imo.

It's about accepting everyone so gays have to be allowed to do everything straight can do
