Did you read what I wrote there? Just in case you did not I'll quote it with emphasis on the important parts:

"One of the differences between this site and the otherwise comparable Reddit is that politics is supposed to be mostly off-limits here where it can run wild on the former site. Had the election been won by 'the correct candidate' (according to the same vocal minority) I suspect that similar griping from the opposing side would have been slammed down hard as being off-topic so my question is: what is different this time around? Why is politics suddenly a relevant topic here?"

It is the rules for thee but not for (D) which I reacted to there. Either all politics are off-limits or none are. Given that political discussions seem to be the new thing here the latter seems to be the case.
