Or, in other words, your constructed argument was in tatters because it relied on the assertion that the cyclist was trying to make the motorist angry, and because you could not defend that assertion you've chosen instead to ask what really is a no brainer of a question.
The problem here is not whether or not it is appropriate to try to make others angry, because it is clearly true that to do so without provocation is unacceptable. The problem is that you interpret the smallest, slightest response, glare or comment from a cyclist as an attempt to do so, you expect of cyclists absolute passivity in response to any and all kinds of provcation, which is neither desireable or very likely. To take such a thing from the context it was in and then insist that it is unlinked to the original topic is insulting to the intelligence of anyone who participated therein.
Ultimately, that makes your poll useless.
Ask another, I dare you. Ask whether it is always inappropriate for cyclists to talk to, look disapprovingly at or mock by action or word the actions of motorists, because that is exactly the position that you have put forward in multiple discussions here, as you have missed few opportunities to criticise cyclists for any and all such actions.
