Considering Hispanics are against gay marriage and they are rising, I don't think gay marriage actually will have a long future in the US. It will go through phases of white liberalized legalization then will likely be repealed and overturned by future Hispanic majorities.
People forget that the entire 'Gay' movement is highly reliant in every way on white political culture. Once that starts to decline, so will gay marriage legalization.
I don't agree.
I think maybe short term, yes, perhaps gay marriage will become legal in some liberal states. That said I think that in 50-100 years the country will have changed so dramatically in terms of racial politics that Hispanics will overturn many of the pro gay laws.
It's generally a rule that where white liberalism declines, the reforms are rolled back. Frankly though I don't think it will even matter. In 50-100 years the gay movement will have collapsed due to a collapse in white liberalism. So it's a mute point.
For example. In 50 years, what will it matter if gay marriage is legal if gays are openly shot in the street in broad daylight? How many gay marriages do you think will really occur in those times?
