In the sense of mocking others, I do not support that style, if you have something to say about someone else it's a much better choice to make it constructive instead of threatening but whether you like it or not this guy clearly knows his business...
You must be new to the interwebs.
In a large number of instances, you cannot deal with trolls, corporate shills and disingenuous posters by using politeness, logic and constructive ideas (facts and logic)...
Sometimes, you gotta play hardball with these nutjobs in order to make your point clearly and unambiguously and not coming off as a pussy.
Sure, frequently, nice and polite can work to possibly give the troll/shill one or two chances to redeem themselves from their seeming lack of substance, but some nutjob posts are decently obvious from the get go.. and frequently the nutjob has no right (and there is little to no benefit) to treat them with kid gloves when they have already shown their colors. So, actually, if nullius or any other poster, such as TMAN were to go a bit overboard with his/her criticism of a seeming troll, the seeming troll could fairly easily redeem themselves by attempting to be constructive or backing off, but instead, what tends to happen is that the troll doubles down or posts some other kind of nonsense that proves that the earlier criticism of the troll was not overly done.
