Rebuttal is incompetent; non-argument
Incompetent rebuttals are arguments where the salient premise is based on: [highlighted pertains to your comment]
non arguments, a non argument isn't really debatable or it's not worthy of debate owing to any of the following types, they come in many different flavors, especially those which contain vacuous declarations and/or allegations (which cannot be substantiated, i.e., 'making stuff up' or repeating some manufactured group-think narrative that is essentially drivel), rebuttals rife with weasel words ( improper use of generalities such as 'some people are saying' 'everyone knows' 'well-established fact'.) ad hominems, loaded terms & phrases,, off topic/irrelevant deflections, sentiments (words that reveal emotional attitude devoid of fact, logic and reason) off point arguments/deflections (off point is a sibling to off topic, where off topic is attempting to highjack the thread. It's done a lot in internet forums, and if the person to whom you directed the topic change accepts it, then you're off into a new direction, but, as such, of course, doesn't refute the original premise offered), egregious strawman arguments, off-the-charts ill-logic, 'kill the messenger" tactics, i.e., attacking the person presenting the argument rather than the argument, itself ( the only time kill the messenger is valid is for a well-established discredited source, such as Alex Jones, David Duke, etc, ), childish remarks, trivialising your opponent's argument -- cheap shot, childish or sophomoric comments arising from ignorance (for example, NYTimes is a 'radical leftist rag' -- that's a remark born out of ignorance, it's also an 'kill the messenger' tactic) and then there is the classic
thought-terminating cliché; these are cult-tropes, born out of groups who have a demagogue leader who is the master of implanting them in his flock. See, the demagogue doesn't like dissent, so when anyone challenges someone in his flock, he, being a master mind manipulator, will have planted a number of thought-terminating clichés into the minds of his subjects ( via repetition) so they will toss it up to the opponent in an attempt to kill the conversation ( wrongfully thinking it improves their argument ) so TTCs are simple terms catch phrases or words whose sole purpose is, to kill the conversation, such as 'TDS' "NeverTrumper" "Leftist Loony" "Liberal elite" (noting that the terms are not necessarily devised by the demagogue himself, they could be created by other believers, or have already been around and adopted by and they catch on with the group ) etc. last, but not least, and a significant debate sin, is posturing; posturing type comments, come in two basic categories, one is where you flaunt, i.e, for example, your military service, but of course if the argument can be improved by your qualifications of expertise in a field, that is okay, what I mean is something like 'I served while you were dodging the draft" whereupon your service doesn't improve your argument about whether dodging the draft was moral, or not, or flaunting your education, or authority of some kind, unless it's pertinent to the argument, and the other type of posturing are those comments which are motivated by puffing oneself up, and this is done by shaming, belittling, mocking, patronizing, 'mansplaining', flaming, where one talks down to ones opponent in order to puff oneself up.
