Feminists created the rift between genders, not male-rights activists.
Yeah, that's like blaming MLK and the Civil Rights Movement for causing the rift between blacks and whites in America!
It's already been covered, but you are creating a scenario where history began with the Feminist Movement...although you don't specify whether you're talking about the 2nd Wave feminists of the 60's, or are going right back to the Suffragettes - who started it all. No recognition of why women were feeling oppressed by a system that didn't give them a right to vote; a right for married women to own property or apply for loans; a right to refuse sex (in Canada, a husband...even an estranged husband, couldn't be charged with rape or sexually assaulting his wife before 1980); a right to equal pay for equal work, and the related right to apply for jobs that were arbitrarily restricted to male applicants by the employer.
As an anecdote, from what my mother tells me of her post-war experience after my father came back from Europe, he didn't demand that she give up her job as a factory floor supervisor/manager when WWII came to a close. They weren't ready to start a family immediately after the War, and he was fine with her continuing on working -- but her employer fired her because they said that "men returning from the War needed those jobs." As a consolation, they offered her her original job as a line worker that she had at the start of the War, and she refused. And during that time before 1950, when my eldest brother was coming along, she wasn't able to find any work equivalent to what she had during the War....and that was likely the seed that spawned 2nd Wave Feminism 10 years later...in spite of the bustling economy and the onslaught of Suzy Homemaker themes directed at young women and girls at that time to just find a good husband and have lots of babies. Most women of my mother's generation didn't become placard-waving feminists, but they still felt cheated by the way their choices and roles in life were so restricted by social convention and the laws of that time. Most women of that era, like my mother and a couple of aunts, plowed their ambitions into volunteer work -- which was often as challenging and demanding as most paid occupations, even if it only offered intangible rewards.
But with all this, you blame feminists for creating a rift between men and women! I would conclude that the anti-feminist backlash reactionary movements (first one I was aware of was in the late 70's) were the source of the rift.
When you have politicians like Hillary Clinton parroting such quotes as "Women have always been the primary victims of war," men start to wake up and realize their contributions and lives are going unnoticed.
I haven't read far enough in this thread to see if anyone has responded with the numbers, but Hilary Clinton is exactly right that (I believe the exact quote is "women and children") are the primary victims of war, because the last war that consisted of massing armies across fortified lines at each other was WWI. If I recall correctly, 90% of the casualties of WWI were soldiers; but by the time we get to WWII, we already have civilian casualties of 50%. And each war since then has saw those civilian casualty numbers rise. Estimates of civilian casualties of the Iraq Invasion and Occupation, range anywhere between 100,000 and one million....far more than the few thousand actual soldiers who have died in the War. And, since Hilary Clinton has traveled to areas like the Congo, where thousands of women have been violently raped (needing reparative surgery afterwards, if they can get it), the long, long ignored backstory of rape and sexual assault of women, and even boys and girls trapped behind enemy lines is another reason why they are victims who have no say in a drama that is carried out by warlords with bands of young men.
