Really, there are a large number of groups, with overlapping members, interests, aims. Some are labeled feminist, but are not really or solely within the feminist movement, and could be said to be biased in one way or another. One area is what could be called the "domestic violence industry", these are writers who push a status-quo version of what domestic violence is - that it's 100% men hurting women, caused by male power, and thus the solution is these re-education programs for men that have been shown to be ineffective, and they *actively* campaign against effective treatment programs that have different assumptions, because that is seen as an attack on their precious "theory".
Some evidence is in this article, below. It shows a broad symmetry in Partner violence rates in bulk studies over the last 30 years, and illustrates actual examples of how that raw data is then doctored to fit the "only men are violent" party line.
Written not by some MRA. But by a PhD in psychology who basically wrote the book on domestic violence back in the 1970's. Because he doesn't toe the party line, he's been labeled with all sort of baseless smear attacks, like that he's a wifebeater and stuff. Neat the end of the article he lists some smear attacks launched against himself, and other colleagues both male or female, for even daring to publish raw data that doesn't fit a political agenda. So, existing evidence is either distorted or selective ignored, and many of those who continue to do the basic research free of an agenda find themselves self-censoring because they fear these reputation-destroying witch hunts.
