Well I think that you have to define what you mean by the far-right. If you mean someone like a white supremacist, then that is an erroneous claim, white supremacists are actually alt-left, but if you mean someone who is on the far-right, someone like myself, then in all honesty, and as someone who used to be on the left, I have never encountered a situation where someone who is engaging someone on the right has been met with screaming and other rude behavior.
It usually goes something like this: EXCUSE ME I'M SPEAKING, YOU'RE AN (INSERT TERM HERE), MORE SCREAMING, YOU'RE JUST WRONG AND A, (INSERT INSULT HERE), BREATHING HARD, I DEMONIZE YOU, SCREAM SOME MORE, RUN AWAY, BREAK SOMETHING, COME BACK AND INSULT AGAIN, TALK OVER YOU, SCREAM, RUN AWAY
Other than the occasional 'snowflake' comment I haven't seen any such behaviour from those on the right who want a civil discourse, except when something such as an insult is almost certainly warranted. For example, when Ben Shapiro called someone an a****** because they were constantly degrading his character.
