I abhor Trump and the values (or lack of, to be more exact) he represents, but I didn't vote because for me too much depends on the relationship in question. If a person has enough redeeming qualities on their own, then perhaps I can look past their support of Trump. I wouldn't be likely to form a close relationship or friendship with anyone who actively supports racism, locking up children, white supremacy, lying, destroying the environment, corruption, wooing dictators, destroying democracy and norms, and all the other things Trump displays. But I'll say that many of the Trump supporters I know (and even love) are woefully ignorant about Trump's debasing behavior. I don't approve of their ignorance, of course, but they are not bad people.
You know that many believe Obama was active in all the bolded areas, right? (Destroying democracy and norms and all the other things would include wiretapping journalists (James Rosen, 20 AP phone lines); Killing US citizens with drone strikes; asking the FBI to keep them informed of the new admin when out of power; etc.) Therefore, welcome to the libertarian party for everyone that said yes.
This is completely disingenuous, whether Republicans or Libertarians are doing it.
Obama "locked up children" technically yes, but as a last resort only when the law absolutely required it. Trump made a show of eagerly tearing families apart with no capability or plans for ever re-uniting them in order to dis-incentivize misdemeanor border-hoppers.
The "lying" bit is probably referring to being "able to keep your doctor/plan" under the ACA, which may not have been universally true but was still true for the vast majority of people. Most people's insurance plan did not evaporate after the ACA.
Obama and corruption? How? Just because intelligence agencies acted on information about the Trump<->Russia connection, a lot of which has been born out in subsequent investigations?
Obama and dictators? Again how? Because extreme partisans claim he "showered them with cash and concessions", aka actually negotiated with them to further the US's interests without starting a war?
No one seriously believes that killing an enemy combatant in the middle of a war is actually unconstitutional just because he happened to be a citizen, not even Republicans.
I can't find anything saying that Obama wanted the FBI to "keep him informed after he was out of power", got a source for that?
You can equate the Obama administration and the Trump administration all you want, but I doubt any reasonable people who lived through both are going to be convinced. They're simply not comparable.
