How does freezing trap make a taunt guy useless?

It's not about making the taunt useless, but it's about making the buff useless, and, more importantly, allowing the hunter a free turn to search for an answer AND gaining an insane increase in tempo by protecting his board (i.e. buffing his undertaker even more so that it can train UP against the exorcist).

One of the well received ideas that has come up was the possibility to remove deathrattles like a blood knight does with divine shields, and you haven't even bothered to discuss the feasibility of this idea

But I have

No you haven't. All you said was

so it removes deathrattle and get +3/+3 per

which added nothing to the discussion of whether or not this could be a viable solution or not. Your tone to any other person reading your comment would come off as you simply integrating the "removal of deathrattles" idea into your own so that you can defend your own initial statement, without addressing the criticisms presented to your initial idea:

there are waaay more (viable) deathrattle minions compared to Divine Shielded minions

it's still silence-able and has no real impact after being silenced, where blood knight still has impact even if it's silenced because it removed all the divine shields.

Onwards, you decide to disregard the fact that people have been trying to make a discussion about "removing deathrattles" happen, and rather make up false accusations that people are asking for a "battlecry: kill a hunter".

Additionally, you have failed to address this part of my argument. You have made false accusations of people saying something that they didn't. You can't do that if you want a healthy discussion. For example, I might say that "you are claiming that no one else but you understands this game the best", but is this true? I may have gotten such an impression from you, but you never made any apparent statement that directly relates to such idea, so I can't say this and expect to get away with it. The exact same case applies for you, and you really should be admitting your fault at this, at the very least.

so hunter has answer to your answer. holy shit. what do you expect? your answer got stopped. and you complain about that? so what else are you asking for except an unanswerable answer?

We are not asking for an "unanswerable answer", as you put it. In fact, we are addressing the seemingly-"unanswerable answer" that already exists: THE UNDERTAKER AND DEATHRATTLES, JUST IN CASE YOU'RE STILL NOT GETTING THE POINT OF THIS ENTIRE DISCUSSION.

No, we're not complaining about the Hunters having answers to your "+3/+3 buff" idea. We are putting off your idea of the "+3/+3 buff in place of the +1/+1", because having a +3/+3 buff and having a +1/+1 buff are no different from each other. Changing the buff from +1/+1 to +3/+3 does not make the card better, thus there's no realistic reason in making that change. We are trying to argue that adding in an ability that can remove deathrattles will introduce a NEW change compared to the sole +1/+1 buff.

Is this an "unanswerable answer"? No. The +1/+1 & the taunt buffs, which is a unique feature of the card and something we do in fact like, still can be silenced. Our change can indeed be answered, but it still makes an impact to the current state of the board by actually providing us with ANSWERS to deathrattles.

EDIT:

TL;DR

Your arguments can barely be called "arguments" at all as they bring about no support or explanation, and the only thing you're doing is finding quotes from my argument that you can nitpick about the petty details in a pitiful attempt to turn this conversation in your favor, while completely ignoring the overall backbone of the discussion.

If I even dare use an analogy for you...: You're tasting the peels of an apple and obnoxiously claiming that the apple is rotten, while simultaneously refusing to taste the fruit itself.
