well sure, if the issue is framed only in the context of what adults do in private - then the balance shifts.
but as we all know, that is not the true agenda here for the gay activists. they don't just want tolerance, they want acceptance. and those are two totally different things. acceptance will turn the public schools into recruitment zones for homosexuality. confront your relatives with that reality.
After 16 years of public school education I doubt if that would make much difference to them. Most young people have drank the Kool-Aid of the NEA/homosexual agenda they have been fed since kindergarten. They are both solidly, economic conservative heterosexuals, but when it comes to homosexuality they just see it as a 'not my business what they do' issue. And I don't think they are in the minority in their age group. I told my wife if the homosexuals would just sit back and wait a few years they would get everything they want without a fight. Their problem is they are totally into immediate gratification, as in I want it NOW. And sadly with the help of activist judges and the USSC they are getting it now.
