Sure, discourage me. Come out in the public square and let's have it out. You use your powers of free speech and persuasion and convince me I'm wrong. If I feel strongly about my opinions, I'll do the same to try to persuade you that you're wrong. Democracy at work.
Start poking around to find whatever job I have and then try to get me fired? Really? That counts as "discouragement" in your book?
You realize, of course, that there are some folks with really nasty opinions out there, folks who would do all the things you mention. Folks who would bring back slavery. And so on.
I must have missed the big public outrage over these folks where we try to get them fired and otherwise interfere with their personal and work lives because of their political opinions. I also missed the part where this became acceptable behavior.
