An 'ad hominem' is an attempt to undermine or discredit the person making the argument, as opposed to addressing the issues raised in the argument itself. That is what I learned when studying philosphy at University, by the way, and that is precisely what some posters have tried to do in this thread.
Wikipedia is not bad on academic subjects such as philospophy, maths, etymology:
Ad hominem - Wikipedia, the free encyclopedia
An
ad hominem (
Latin for "to the man"), short for
argumentum ad hominem, is an attempt to negate the truth of a claim by pointing out a negative characteristic or belief of the person supporting it.
[1] Ad hominem reasoning is normally described as a
logical fallacy,
[2][3][4] more precisely an
informal fallacy and an irrelevance.

However, the particular
name of the thing is probably irrelevent.
Edit: For the record, saying that a particular opinion is a minority one, thus can be discounted, has a different name AFAIK, but I don't recall it. It's still a recognised fallacy. However, most of the alleged "ad hominem" accusations here are off-target, posters are accepting the problem phrased in the OP, and after trying to present their own answers, are suggesting work-around fixes that might work for you and allow you to play the game. The assumption being that something that blocks a poster here from playing a game that they like is worth some creative thinking to solve.

You are complaining that posters are not addressing your
issue, but are instead pointing out you have options to ignore your problem with the Halfling racial weapon die upgrade.
The reason for this is because the underlying
issue is - in the game (I'm not referring to your concerns, which are real of course) - a complete and utter fiction. Hit points are so far from capturing the essence of damage and injury that there is no possible logical, real or verisimilude-based argument that cannot have its foundations cut out from under it. Add to that your dislike of any "gamist" answer, and there is literally no reasoned argument that is going to work for or against the hobbit damage.
The Halfling damage dice for preferred weapons is pure gamist. It can be supported by numerous plausible game-world fictions. If you find them lacking, you are left with just the pure gamist side, and if that's still bad for you, you can complain to the game designers and/or houserule if it ever crops up in your own games.
When I posted that you'll probably have to live with house-ruling it, that's a prediction of how things will pan out, not an instruction to not bother giving feedback. By all means give your feedback on the playtest, it's what it is for. There could well be a silent majority, whom I don't usually encounter, or unaware of this thread, all saying the same as you. In which case WotC would be well advised to find another way to make Halflings balanced characters. WotC also have room to re-define what "balanced" means, because there plenty of ways to cut that, too - I think there's a few other threads for that
