It really does look like they created a monster that has gotten out of control. I can't say I feel badly for them, but as a US citizen, I can say this shit (and the philosophy that lead to its creation) is weakening the country.
You wouldn't say you feel badly for them: I suspect their tactile sensations still work, even if they may be inured. You would feel bad for them -- "feel" is a linking verb so it gets an adjective. Actually, I do feel bad for them. The right wing is having its own late 1960s. We already know how that ends: they'll burn out and need to recover. No one, even the angry and the bitter, deserves to suffer. They aren't listening, so we can't help them. They have to hit rock bottom. When they do, they'll turn on their former leaders (oh wait, they are). I want to be as far out of the way as possible.
No sweat. I usually eschew my temptation to correct the grammar of others because it comes off as overbearing. I guess if you flush out the flesh, you're preparing a cadaver.
