Based on what? If anything, the left is more about being progressive and creating rights for groups that wouldn't otherwise have those right. If anything, the left would just have a less hard of a time granting those rights. They're far from being communist or anything of the like if that's what you're implying. Even if that's not what you're implying, that's literally what it would take for rights to be taken away.
And then to think the left here would be cheering that on. Again, based on what? I don't see anyone here cheering on taking away rights on the left... because, again, it's the opposite things the sides are trying to work towards.
Honestly, your post couldn't be more wrong. It's playing make believe that both sides are exactly the same when they clearly are not. There are some similarities, but more in the way they're attack each other (and even then there's differences). They're very different in terms of policies. Even the MAGA republicans and normal republicans are different and that's just with 1 of the parties.
Perhaps, if anything, this says how little you know about the left if this is truly how you feel. Or perhaps your post was meant to anger leftists in pigeonholing them into something they're not.
