According to book "A Brief History of The Men’s Rights Movement - From 1856 to the present" by Peter Wright:

in the absence of a reliable overview the MRM has been vulnerable to annexing by gender-studies proponents who claim the first men’s movement was launched in the 1970s by second wave feminists. For example, the current Wikipedia entry on the men’s rights movement has suffered censorship of any material from the now century-long tradition of men’s rights activism addressing issues such as unfair divorce law, alimony, criminal sentencing and the like. In place of that long tradition the opening sentence of the Wikipedia article, one enforced by Wikipedia administrative editors, reads:

“The men’s rights movement (MRM) is a part of the larger men’s movement. It branched off from the men’s liberation movement in the early 1970s.”

Few serious scholars would accept that the MRM began in the 1970s, there being numerous examples of well-organized MR activism extending back into the 1800s (See Parts 1-3). Moreover, the ‘men’s liberation movement’ cited in the Wikipedia article was in fact a feminist initiative launched to foster more pro-feminist ideology among men, with the latter movement arising within the National Organization for Women.

The longevity of the MRM has been largely overlooked due to successful efforts to censor its existence. Such censorship is not new..."

QUESTION: Have you noticed that "Men's Rights" wikipedia article heavily leans feminist point of view?
