It's an interesting arms race, where an optimal bot has better chances of surviving than a normal person that will naturally have diverse opinions.
As I pointed out in another comment:
The right can pretend to be antagonizing extremist LGBTs to get more centrists to support their agenda - while undermining the LGBT movement itself also from within.
I'm saying that right wing activist groups can use botnet to pretend to be LGBT, while being hateful and extreme in their views, to the point that "normal" people (who are indifferent about LGBT) become annoyed with "LGBT" to the point of supporting Trump etc.
I'm saying that LGBT groups need to be aware that there is a serious internal threat of people pretending to be LGBT while harassing people who are not against LGBT, but will be.
An alternative explanation is that LGBT people are just a hateful bunch, but I'm trying to argue against that hypothesis.
