Well, when you end up segregating people by ideology you virtually guarantee it and with only two major parties you facilitate the building of coalitions over things like religion, LGBT rights and gun control. Hence it’s become the rural right against the urban left locked in ideological battles over these kinds of issues.
80% of Republicans do not believe there is such thing as being transgender while a healthy majority of Democrats do. It also won’t surprise you that the credibility of transgender people improves with the level of education of the voter. This is more true in the Democratic party than in the Republican party which contains more hard line ideologues; for them it is dogmatic conservatism that drives their thinking.
Divide and conquer by wedge issues wasn’t always so prevalent and Republican voters who are libertarians have been left with little choice but to align with a party that increasingly does not represent them; a party full of hard line evangelicals and increasingly alt-right elements that flirt with fascism. These factions all play in the same sandbox now and fight for the soul of a party which is harder to define than ever.
Transgender people have gained the most visibility ever but the violence against us is at an all time high which does not surprise. The more radical elements cannot abide by these advancements and are doing what they can to undermine our credibility and stop our infecting of society with our so called "agenda".
