I never start any fight with anyone unless someone starts insulting me by calling established facts "bullshit" or "your bullshit theory" while not knowing that it is not my theory but well known textbook fact or math.

How can someone not understanding physics argue about it in the first place? Say, I know nothing about Francis Bacon or Aristotle - so I am simply not qualified to argue about their point of view. And I do not, because I simply do not know what to talk about.

So when people with no physics background argue about physics and I know that they are incorrect -what should I do?

Should not I say that they have to learn information they want to argue about FIRST?

I actually patiently educate most of them without pointing on gaps in their education/understanding of physics, unless they insist on something profoundly contradicting to basic facts or basic math (=logic).

It is fine to purely speculate about, say, multidimensional time - with clear understanding of no relation to reality. Another thing is to point on possibility of actual time travel - this breaks basic logic the whole math and physics rests on.
