Absolutely! The groomer rhetoric gives people cover to state and work for anti-gay positions that they would not ordinarily even feel free to articulate. "I'm not anti-gay, I'm just anti-groomer." Then off they go championing anti-gay positions pulled straight from the 1970s.
Gay people who fall onto the anti-trans bandwagon should think about that. The same social conservatives who oppose transgender rights and visibility oppose gay rights, every bit as much and in some cases even more.
The groomer label is just a fig leaf that gives them cover to express their bigotry.
We should pay attention when social conservatives act like they can't tell the difference between drag queens, transgender people, and gender-bending gay people.
They generally are not interested in distinguishing, because they don't care about the differences. It's all objectionable to them, but they'll be perfectly happy to divide and conquer.
