FHN, correct me if I'm wrong on this, but what you're doing looks alot from here to be tone trolling:
A tone troll is someone who, in the course of a debate, dismisses an opponent's argument based on perceived crassness, hysteria, or anger.  It's a particularly slimy form of ad hominem attack beloved of Very Serious People, and its sliminess comes of it being quite commonly deployed against opponents lower on the privilege ladder. However, the phrase "tone trolling" itself can be used to excuse verbally abusing one's opponents, so be careful who you accuse of doing it.
As a debating technique, it can theoretically be employed honestly (in response to emotional appeal), but it's not a very good argument because it focuses on style over substance. Rather than addressing the central claims of an argument, it focuses on superficial, "shrill" features of said argument, which inherently isn't that logical. Tone trolling in practice is almost always dishonest and therefore kind of creates an "appearance of impropriety" situation.
As pointed out in the article, the focus should remain on the substance of someone's arguments, and NOT their style (within limits of course), since the truth of a matter doesn't depend on the style used by the one delivering the message (where the message SHOULD remain the focus; for as the Bible says, out of the mouths of babes come truths).
Of course practically speaking, we all know that style DOES matter, which is exactly WHY JWs want their members to maintain a clean-cut look, wear a suit, etc. They exploit the tendency of most people to give more credibility to anyone who's wearing a neatly-pressed shirt. Obviously, that is a questionable assumption to carry, but you're seemingly demanding a uniformity in style?
Bottom line is that anyone who wants to dismiss messages based on such style issues is free to do so, and is likely already looking for excuses to dismiss others so as to justify ignoring what they say (AKA post-hoc rationalization). They do so at their own risk, since the desire to remain wallowing in their own beliefs doesn't harm anyone but themselves, and certainly not the one who's offering their opinion.
