It’s best just to ignore them. It’s like leaving an annoying, yippy little dog alone. Sooner or later they get tired of barking without a response.Nope. That is like ignoring a weed. It flowers and attracts others. Weeding takes work but the end result is worth it.
The problem is, they’re little more than Obama style agitators. Arguing with them is like wrestling with a pig. You get dirty and they enjoy it.
