It would be usually, but in the case of Trump the campaign of misinformation and organised sustained social programming that took place by the apparatus of the Dems and the US State makes it hard to take any unsupported allegation at face value.

The sheer amount of lies told and events and facts deliberately misrepresented over the last decade to socially engineer hate for this man is unlike anything else ever seen in politics.

I am not saying he is perfect of course, not at all, I don't even deny that some of these may have happened, but show me the politician that is. Clinton? Biden? Obama? Utter sociopaths responsible for mass deaths across the world.

I just have better more immediate things to worry about than politically weaponised unsupported accusations from the 70s, 80s, or, 90s. Even if some aren't politically motivated, I don't trust the human memory to deliver accurate unbiased truth from 40 years ago.
