I’ve heard statements like this from others, and in my experience it simply isn’t true. I find Parisians to be generally polite, not pushy, reserved, and if you’re in need of help, very accommodating. My French is sucky to nonexistent, but with a smile you can accomplish a lot. I find Paris to be much less threatening than many American cities, and beautiful as well.
I said that the French do not like to hear French spoken with an English accent. Since you can't do that, naturally you would have no problem.
