“Men’s rights” has literally always had a toxic connotation.

The term “men’s rights” was used at least as early as February 1856 when it appeared in Putnam’s Magazine. The author was responding to the issue of women’s rights, calling it a “new movement for social reform, and even for political revolution”, which the author proposed to counter with men’s rights.[12] Ernest Belfort Bax wrote The Legal Subjection of Men in 1896, deriding the women’s rights movement as a farcical effort by women—the “privileged sex”—to prove they were “oppressed.”
