V-railing
A conversation derailing tactic influenced by a mindset according to which only women’s issues matter and worthy of discussion and men’s issues are non existent or irrelevant. V-railing is practiced typically by feminists whenever a men’s issue is being raised or discussed. It is used by them as a means to belittle or to dismiss the men’s issue, or to impose their ideological perspective and values at the expense of the worldviews or the other peers.

V-railing is when a person broaches a serious men’s rights issue and a feminist comes in and derails the conversation by talking about how women suffer from it, or expresses the prejudice that women in general suffer more than other demographics or how women's situation is the worst, with or without regard to the issue being discussed. A V-railing may also be preformed by claiming that the only motivation for a man to talk about men’s rights and issues is to get laid or to get pussy.

The "V" in V-railing stands for vagina and implies that in the mind of the anyone who resort to this tactic, anything in the world has to do with vagina (theirs or others')
The word was termed and first introduced by the men’s rights activist and youtuber bane666au in his video: “The inane nattering of the ‘witless bitches’ part 2”
Example 1:

Non feminist: “If you are a criminal defendant it’s better to be a woman than a man. For the same crime with the same criminal history, men in the US are imprisoned much more frequently and for much longer sentences.”

Feminist: “Well, it makes sense since 99% of criminals are male, besides; it's men's fault because we're living in a Patriarchy which hurt all women the most. It‘s women who have always suffered from systemic oppression by men for thousands of years. Fighting rape culture is much more important than this.

Non feminist: "Ooh! that was an amazing V-railing there... :) how typical. What would you expect from a feminist ideologue..."

Example 2:

Non feminist: “There are many issues affecting men and boys today in our society, Just to mention a few major ones: the right to bodily integrity for male babies (genital mutilation in females is against the law whereas MGM is still legal and prevalent), fighting the high percentages of male suicide, fighting male homelessness (men comprise the vast majority of the homeless), helping male victims of domestic violence, sexual assault and rape who's suffer and needs get zero support, resources or public attention, and much more such crucial issues.”

Feminist: “well, Boo hoo! Men’s rights are such BS, you must be one of those MRA manbanies who constantly bitch about "men’s issues" only out of frustration from never getting women to like them, let alone fuck with them.”
