While it's correct that most men have never heard of the MRM, the messages have reached way more than you think. I see them grow in my own very blue-pill social circle. I keep my mouth shut and say nothing except through humour, and I keep hearing guys bringing up topics related to the MRM and saying how they're sick & tired of feminist bullsh1t (e.g the 77c to a dollar one). Nobody is active in spreading the message IRL, but those guys are finding them all on their own, thanks to the Internet.
Besides, no guy wants to admit this IRL due to lack of anonymity. If you talk to me in my social habitat, you'd hear mostly blue pill crap, although if you pay attention, you'll recognise plenty of red pill knowledge sprinkled here & there.
There are so many feminists in my circles (a very SWPL city) that I have to protect myself. Laws of power baby.
Articles like this one are great for us. Even when they publish their denials of any war on men or issue affecting men, they are giving our issues publicity. Naturally men will read this and their minds will wonder if the issues truly exist or not. Getting them to think about men's issues (hopefully before they get bitten in the arse by those) is a great start.
