Dude, what on Earth is everyone going on about? Parler doesn’t run on WordPress. Anyone who’s ever ran a WordPress installation should be able to tell that.
If you have a Parler account, you should be able to check the page source or use Chrome’s element inspector to take a look at the page elements.
WordPress sites are pretty obvious. A quick peek at the elements or page source should show it’s not WordPress. You can obscure some of that with a custom install, but, like, WordPress source code is really identifiable.
Also, if you were going to go to all the hassle of rewriting enough of the WordPress source code that you couldn’t tell it was WordPress anymore, why would you even bother building on top of WordPress?
