The only people trying to argue "lighten up" are anti-feminists.
On the other hand, "The only people trying to argue "lighten up" are anti-feminists" is a nasty false generalisation -- it ignores apath-feminists (damn, that doesn't work nearly as well as 'apatheists'); those who are thinking "can't we all just get along?", with absolutely no motive to stymie feminism; those who've never done the research, who think feminism's all well-and-good, but tell themselves they're too busy worrying about other things; exactly the sort of people who would find that article insightful, and who might be pushed toward feminism by it.
I fear you risk scaring them off by lumping them in with 'anti-feminists' and its implications of misogyny, and may taint that link by association.
I think it boils down to the technical meaning in feminist theory of 'anti-feminist' (anything that holds back feminism) not really matching up with what the layperson seeing the word for the first time would take it to mean -- 'anti-feminist' intuitively sounds like it only applies to active, concious opposition to the ideals of feminism; misogyny, denial of female autonomy, Rush Limbaugh, that kinda thing. Laypeople may not think to also consider apathy that unwittingly enables the sexist status quo as part of anti-feminism.
I'm definitely not saying you're wrong, I'm just saying you risk alienating your target audience by... well, to be flippant, by using big fancy words they may not understand ;)
I do agree that sexist jokes are a bad thing and not only when done against woman.
But most groups who say "I'm not anti woman, just anti feminism" are flat out patriarchal, whether the flavour is religious or "men's rights", it's the same garbage.
And I won't accept it from a man at all.
Unfortunately my perception is similar to yours. I have seen enough nut case traditionalists and misogyny to not want to get involved with mans rights movement. Traditionalist ideology hurts MRM and I feel they are shooting themselves on the foot by allowing this sort of thing.
This is why I can't see my self associating with MRM or Feminists. Both groups can be pretty extreme although both have some (in my opinion) good goals like womans rights to choose & legal paternal surrender.
Thank you for your comment.
edit: I must say that I have seen MRM people against traditional patriarchy. Their idea is that a patriarchy does not allow men to be free.
If they admitted that, they'd be feminists.
I see the sexual objectification concept often used as a way to demonise natural human sexual attraction. If man and woman ignored physical appearance and resourcefulness we would probably be extinct by now.
