OMG, you don't know blader? He's the person that you should be challenging and shutting down, not blocking. While I do not like blader, its perspective is certainly different from the chorus that exists on TMC. While I find their attitude poor, to say the least, their posts are generally informative and challenge the herd mindset.
Since you are quite knowledgeable, I suggest engaging rather than withdrawing.
I am not knowledgeable enough but I do keep track of how often (and its OFTEN) blader has been wrong.
Remember, blader said EAP in July. Then september. Ironically, he's actually been overly optimistic! Don't let him get away with saying end of 2018/19 like PM_NIPS.
