Yeah, I hate to break this to ya, but if you've "seen" Biden's public speeches from twenty years ago, you'd see he still had a speech impediment - one he's had his entire life and spent a lot of work to control. As someone else who has trouble speaking in public, props to him for rising above it.
And the sad part? People are literally mocking his speech impediment to make it seem like he has dementia when they know the truth - that's like making fun of someone for being stuck in a wheelchair. But once again, it shows the class of the people we're dealing with.

But let me guess, mocking an orange clown for the makeup they choose to smear on daily would be considered "crossing the line" to you, right?
