> Whatever stance changes nothing .. is a vote for the status quo, by definition.

As problematic as the assertion "by definition" is aside, it should be noted that endlessly commenting about politics on internet forums effectively changes nothing.

I've been kettled by mounted officers and hit by high pressure hoses on cold evenings, something that also rarely effects change .. but that's a least a fun night out with people and better than wasting bits on the intertubes.

I wouldn't say that avoiding political discussion yourself because you can't handle it is a vote for the status quo, but telling others not to talk about politics is definitely a vote for the status quo.

No, that isn't remotely true. It means that the alternative you offer isn't compelling, not that your interlocutor likes the status quo.
