I'll go so far as to give you an answer from WT literature why exposing WT stupidity is not wrong. If they don't like what we do here, then they shouldn't have written this:
.
"So, then, when religious leaders and organizations of Christendom misrepresent God’s Word by teaching traditions of men, is it wrong to expose their false doctrines? When they claim to be following Christ and yet mix in worldly politics, is it a bad thing to publicize that their actions are unchristian and condemned by God? Should the truth be suppressed because it exposes falsehood and corruption? Never! Jesus never hesitated to speak the truth, even though he was killed at the instigation of the angered religious leaders for doing so.—John 17:14; Jas. 4:4.
Therefore, how will you respond when pointed statements are made about false religious teachings and corrupt practices? Will you immediately condemn the person or organization making the exposé? Do you feel it is all right to teach lies and misrepresent God’s Word, but wrong to expose the error? Contrary to what some may think, it is not unkind and unloving to lay bare falsehood and corruption." ---W 3/1/66, p. 132
