I don't think it is a misplaced rant.
I think it's absolutely appropriately placed. It was placed just after 2 people (one of them male) got sneery about people taking the piss out of IMD and implied that we're somehow wrong to do so.
I think we have every right to do so but am not surprised to see you popping up here to wag your finger at us.
As for your post, it's full of the usual disingenuous stuff I've got used to from you.
-Of course just about all of it is very badly skewed and misrepresentative of anything I said, and indeed of the stated aims of IMD.
Meaningless.
-No 'assistance' from feminists have been asked for as far as I can see
? No idea why you've said that.
- the analogy of race is an embarrassment for you I disagree, I think it's unpalatable for you.
-the article does say 'fuck off and play whilst we do the important business' (no matter what a productive outcome could be, hence the 'enjoy nursing your grievances' type comment which is evidently justified whether you like it or not)
My rant as you call it, was prompted by your posts, not by the article.
-and men are often discriminated against legally and socially. 
-Re the quoted para, frankly one could point to any wild-eyed, mouth-frothing radfem and claim they represent feminism and so sideline the whole movement for that reason alone.
No you couldn't, but you might be able to sideline the website, depending on what sort of website it was. This para was indicative of the tone of the website as a whole and I think anyone who is being honest will actually see that.
But none of these things interest you, do they? Yes they do Pan, but tbh very little that you say interests me and I find you so terribly disingenuous and dishonest that I'm not that interested in discussing most things with you because I find it distasteful. The only reason I've gone through your misplaced bullet pointed rant here, is because I'm literally waiting for paint to dry before I put the next coat on.
