In one video Biden gropes a young girls breasts.
In another he takes the hand of another girl and rubs it against this crotch.
And then the least offensive is him sniffing kid's hair.
This is not a singular one off incident, and these are not the only 3 such cases either.
Now imagine the backlash if Trump did those things.
I've seen these. They're... weird. But he isn't really paying much attention to the child in the 'groping' (not actually a grope but I know how you tabloid people like that hyperbole) and he doesn't "take her hand and rub it against his crotch", he's just pulling her into position (this is even commented on by the cameraman in one of the versions).
Does that make it better? I mean... yes, sort of.
Does it make it not weird? Yeh, no. It's weird. Mostly because we live in a world where even a hint of impropriety is a slippery slope that can cause gossip and tabloids to run amok for weeks, especially for 'celebrities'. Not sure how/why Biden wasn't coached on how to avoid this kind of scene. My only thought is that he's so old and set in his ways that he still thinks it's the 50s and "personal space" doesn't exist yet.
But actually a paedophile? Highly doubt it. For a start, a paedophile with his HUGELY HIGH level of media scrutiny would only have avoided being caught in some scandal, by long ago learning to hide his predilections. It would take a pervert with some massive balls to actively fondle underage girls -on camera in the middle of the senate-.
So I (much like yourself) have zero evidence on this either way. And as a non-american, I honestly couldn't care less. But I suspect he's just a slightly odd grandfather figure, and not an actual child molester.
But then I'm equally convinced that Trump was a semi-senile moron who has raped at least one women and had a more-than-passing involvement with the aforementioned person who totally didn't kill themselves. But I personally have no actual evidence of that either, and he did get found.... innocent? (Well I mean it was a totally biased 'trial' (not actually a trial I know (deeply nested brackets excite me)) that he couldn't lose, so...)
So yeh, will be interesting to see if Biden does anything interesting. But I suspect he'll be a fairly boring politician. Which is going to be much nicer for everyone who isn't an American at least.
