Respect isn't conditional on getting your way. You're not going to get anything by being "nasty" to the left except cede any moral high ground you could have claimed to have.

If you think we have anything left to do but be nasty to the left, you can go fuck yourself tbh.

You might not have anything left to do, but there are plenty of people working hard for what they believe in. And you're making it more difficult for them by painting everyone on the right like a jackass.
