I have said that continuing to fight this battle only burns political capital, gives the Dems 'boogieman' about the Right wanting to repeal same-sex marriage legitimacy, could drive right leaning LGBs to simply vote third party, and does damage to the coalition Trump built.
A coaltion the Right will need if it ever wants national level power again, assuming the elections process ever gets cleaned up.
There are many places LGBs and even more traditional members of the Right can work together and agree on. 2nd Amendment protections for gun owners, China fucking with all of us, immigration reform (the Right's version, not the Dems illegal immigrant amnesty bullshit), and cutting down on gov red tape are all areas that can be common ground.
I am not saying you have to approve of same-sex marriage, not at all; I am saying that actively talking about wanting to repeal it or use political forces against the rights LGBs have now is absolutely counterproductive to pretty much all the other issues/goals the Right have on their platform.
