There are things that homosexual parents don't want their kids to see (like the S&M macho men) and they realize that the kids will tire out and need to be cared for.
Some homosexuals said that they find themselves having to get more support from their heterosexual friends than their homosexual friends because they can't relate. They are focused on an "adults only world" and don't think about kids. I would add that they think of themselves and don't think about others.
This is why I say that they will push for an agenda that will create more social ills. Corruption of minors? Pshaw, they don't have kids to raise (homosexual parents are a ridiculously small subset of an already small subculture of America). Tax dollars for schools or AIDS research? Which will affect them more?
As a voting block, candidates will appeal to their interests, sometimes at the exclusion of mainstream America.
Deny the kids a good education and the future engineer, surgeon, police officer, food inspector, etc. may not do as good of a job. Even those who don't raise a family should be able to agree that families are a good thing.
