That sounds nice and all, but doesn't say much about why a lot of discussion gets derailed. True, there are zealots who don't help, but oftentimes things go south because of the manner in which men's problems are brought up in discussions touching on feminism. "But what about men's problems, huh? Why are we not talking about them?" - this in discussions about women's problems, which tends to be followed by insults and derogatory remarks directed against feminists.
To try and give a serious answer (despite the pleas of the OP), in my experience on this board at any rate, this "de-railment" usually comes after a topic of policy has been brought up that, while technically about women and not addressing men directly, has some obvious and unfair repercussion for men (in some people's eyes at least), and therefore it's entirely reasonable to bring things up.
For example, let's go with something that always gets brought up in these debates, the fact that 90% of the homeless (or something of that order) are male. Now imagine the government announces a special initiative/programme to help get the female homeless off the streets and into some accommodation, at some cost to the tax payer. Now obviously, on the face of it, this is a good thing - the problem is real and no-one should be on the streets, and good will be done by the programme. But if a man pops up and says "er.... hang on a minute, that seems a bit unfair...", is it really right to shout him down and to tell him to stop making this about men? Is this a women's issue that he's hijacking, or is he actually making an entirely relevant point about fairness?
Or a more ludicrous example, what if the government announced they were giving out free cars to all women over 18 because women are just so great and deserve them? Would "OMG stop making this about YOU all the time!! This is clearly a policy about women, for women. It's not about you, stop trying to make it about you!!!!" be a reasonable response?
I can't, off the top of my head, remember any examples of these arguments on CFC that have started with some entirely fair and reasonable discussion about a genuine female issue or problem, that's being dealt with in a reasonable way, being suddenly hijacked by an MRA demanding we talk about men instead. It's usually in response to something stupid like subway signs telling all men to never talk to women and stop openly masturbating all the time.
