Yes Trump has taken in money from KKK supporters. So that means he approves of their message now, by your broken logic.
I take the Reagan approach. Those who endorse are signing on to the message of the nominee...not the other way around.

You draw no distinction between inviting someone into your campaign vs. someone sent you $10?
There is a greater standard of care adding someone to your campaign committee than accepting a small donation where he only information to the donee is a persons name, address and place of occupation (often filled in as “retired or self-employed”)
Do you have a link for those KKK contributions? I would like to see if it was returned.
But by all means, please send that along.
It depends on what the issue is. If the issue is someone is a murderer and rapist or racist then yes extra care must be given (even in accepting support from those people). If the person is willing to back the candidates cause and his only crime is he’s a liberal (like Trump is) then it’s ok as long as he is advancing the candidates platform.
