I agree entirely. It's a provocative, flame-baiting statement.
And Rob makes a good point, too.
Not much to add to that...
Yet you list Entwistle, who did some of his most influential work on a t-bird and, later, his "Fender-birds" and probably did more to popularize the t-bird than anyone, as an influence -- as well as Squire who also used them. And your profile pic is with one of those Mark Hoppus basses - which look a bit lame to me - but if it works, which I'm sure it does, then cool -- but I'm not going to say you can't play just because you choose to play a bass that I wouldn't (at least, I wouldn't right now, maybe I'll change my mind at some point just like I did with thunderbirds).
Here's a bird pic I took from the stage this summer - he was playing and sounding great:

A lot of the comments on this thread remind me of the kind of conservative mind-set that 'greeted' the electric bass when it was first introduced and dismissed it as an "inferior" toy and not a 'real' instrument.
