I imagined a cock slap.

This is a ‘Rob my house, I have guns inside’ sign.

Have your wife kick his ass.

Ever seen a leftist fight?

seriously though he will do something violent and wife needs to be done with

Like, literally cuckold the guy.

Maybe you should try and sell him a bumpstock or NRA Life membership?

You need to live next to people like that with your own range.
When they go nuts, time to go blasting.

Be careful with unstable Leftist nut jobs.

One of them put Rand Paul in the hospital.

Leftists love to argue and fight. That way they can counter-accuse you of wrong doing. A "he-say--He-say" situation.

They love to spin shit around and then claim they are the victim when in fact they are the instigator of their own shit storm.

If you get one of those signs on your front lawn, get lights and cameras as jack-off is almost sure to steal or vandalize it.

It would be nice to have a compilation of videos documenting his harassment of you and your wife.

"A picture is worth a thousand words".  A video (with sound) is worth 10,000 words.

If you're such an evil fuck, maybe he should shut his suck.

Turn his children against him and convert two more to our side.  Invite them all over for Thanksgiving, after his kids have converted.

Easier to lash out at faceless strangers on a board than stand his ground in his own house. One doesn’t have to be aggressive when countering liberal viewpoints. In fact, in one’s house one could simply let it made known that such discussions are verboten. Plenty of things to talk about besides politics.

Why membership?  I'd bet you could get him on the mailing list without membership.  that's a hard list to get off.  Especially if they have "your" phone number.

Why the fuck has this person's wife been allowed to befriend your wife? I sure as fuck would not allow that buffoonery anywhere near me and my family.

Take one for the team ,OP.  If we ban you, then there will never be another school shooting, right?

Yeah, if someone had done to my wife what you say this piece of shit did to yours, he'd be hitting the dirt.

My first thought too but I would call the POPO to document that he is an asshole first.

As a general rule, it is understood around here that if a man has a problem with another man, he talks to HIM.  You NEVER talk to a man's wife about her husband.  And who the hell knows what women do.

Point is... the man addressed the OP's wife because she was the safer route.  He wants to lash out, but lacks the courage to do so directly.

This is a man that will allow you to jeopardize your gun rights when you handle it as a man would.

The only course of action that actually has impact is clear:

Next time you see him around tell him that if he has a problem with you, he needs to come to you and not run to his wife like a coward.   Don't curse him.  Use firm but nonthreatening language.

And walk away.

Everything that the OP has posted indicates that this man is living in his own hell of his mind.  He is unhinged, lashes out, and is damaging himself in the eyes of his own family.  There's no better harm one can do to him than be an example of what he will not and cannot ever be.  May be enough to tip him over.  You don't have to say you'll do anything to him if he speaks to her again like that.  A lion doesn't have to tell you it will eat you for you to steer clear.  It just has to sit there doing lion shit.

That could be his brother.
