It's not a skewed poll.
Of course it's skewed: all polls are. This one happens to be skewed in a very clear and particular way, towards a particular answer. The original post tells the reader that "the mechanic causes the hit point mechanic to break down."
The only purpose for such an unsubstantiated claim is to encourage a specific result.
The OP also insists "just because something is balanced, doesn't make it good." That too is an opinion designed to taint the sample. If you want to remove the appearance of skewing while keeping these poll options, I would suggest you remove both of these statements.
As it turns out, you do believe that there is mechanical balance:
Mathematically is [sic; "it"] works but there is more to the game than just math.
You just happen not to care.
Would you be willing to re-write the OP to say clearly
(a) that you believe the mechanic as implemented is mathematically balanced against the other options available, and
(b) that you recognize that it only affects a small number of characters and requires players to choose a given build within a class, denying their characters other options, and
(c) that given that you are only interested in a poll on the (internal) believability of the mechanic?
You know (a) and (b) to be the case, and you know that they are important factors in the discussion. If you choose to exclude them, you should admit you are doing so. Mentioning them up front would help make the question asked by the poll somewhat less stilted.
