I'm sure you'll admit the Dems have many, many issues. The question then is why you believe they are "focused" on sexuality. I propose it's because you find their stance on sexuality to be problematic in some way: it bugs you. So what you are saying is "don't talk about the thing that bugs me." [Quote]
You have missed the point while preaching to the choir here.
Mine was that there are much bigger fish to fry than silly issues such as "who goes where". (Yes, that's a BR reference.) Our very existence as a democracy is at stake in 2020. Imagine what Trump will do with 4 more years at his disposal.
And, if the Dems choose to make sexuality -in any form- a central plank in their platform, it's at their peril.
Take that to the bank.
