From where I sit on the left, the right wing is extremely effective in making people believe the left is a parody of itself.
For instance, the left does have stronger support for LGBTQ issues than the right, but it isn't the primary issue. I'm sure "Build Back Better" investments in infrastructure involved 100x the attention and resources that LGBTQ issues did. But right media pushes stories multiple times a day about how the left is trying to turn your little Johnny into Janie. There are fewer than ten M->F trans athletes in college sports [1], but it is nearly a daily news item. The the casual news viewer (most everybody) their impression watching their news is that the only concern of Democrats is to advance a LGBTQ takeover.
Same thing with CRT. Same thing with Benghazi. Same thing with Hillary's emails. They pick an issue and hammer it, hammer it, hammer it. And it doesn't stay stuck in the right wing mediasphere. It becomes part of the "national conversation" and so mainstream media has to report on it too.
