I was just sitting at the mall taking a break from mall walking. A man walked over to me when I wasn’t even looking up. He said "I haven’t seen you here before. " I said I wasn’t really here to talk to people and got up and walked away. He said he would leave, he may even have said sorry. I said I was ready to leave anyway. In retrospect I think he may have just been slightly mentally challenged so I wish I had been a little softer, he did not turn out to be aggressive. Looking for suggestions on something still clear and firm but more polite? This scared me for some reason, I think how fast he walked up and sat down near me.
Editing to add a key detail, he sat down close to me which is probably what made me more nervous than I would have otherwise been. I appreciate all the thoughtful feedback I’ve gotten and interesting discussion.


I find this highly unlikely. Both stem from your internal sense of morality / your values / the way you see the world, and will be influenced accordingly and therefore very related.
Speaking of which:
A third of the US voted for the latter. Anyone willing to put him in charge is delusional in their judgement to the point that I would consider myself in danger if I needed to rely on them. Not to mention that, as above, their moral axioms are likely to be disgusting, and that affects how they will treat me. Most social interactions can go fine, but any sort of extended relationship will not be.
