Nice disparaging comments on Kennedy and Johnson; also nice whataboutism. As is typical with whataboutisms, the reflect on the fact that you can not defend Trump, so you try to change the subject. The problem is, there are no equivalent "whataboutisms" to Trump. You are trying to deflect from a murdered by trying to have a conversation about people that park in no parking zones.
Yes, Kennedy and Johnson each had character flaws, but they did substantially have character. Each had a love for America, a respect for the rule of law and were in awe of the office of the Presidency. They may have not been choir boys, but in terms of sinners, they each were quite saintly compared to Trump.
You are just failing miserably in your ability to comprehend just how dangerous Trump was (and is). Just the fact that he presided over the 1st non peaceful transfer of power in American history should be sufficient to have you despise the man. If that doesn't make you uniquely hate man, then think about impact to our democracy of his fabrication of the notion that there was something wrong with the 2020 election and that he managed to convince a large part of our population that American election outcomes should not be trusted, which has served to weaken this country in a way that no man has ever done. You can not have a strong democracy when 30% of the country doesn't trust the election process. Of course, this is in addition to being impeached twice, under federal investigation for his fraudlent election activities. He is not a good human being by any measure.
Look if you want to like Trump's politics, well that is one discussion; but to not see his obvious and dangerous character flaws, well, if you can see them, you are a very bad judge of character. Johnson and Kennedy may have had character flaws, but they were not characterless, as is Trump.
