I think what Schlichter is saying, and I know I will be corrected if I'm wrong, is that conservatism has become synonymous with not fighting back while being sure that that position is the only true one. Schlichter says that Trump fights back, therefore his is the correct attitude.
I would disagree with Schlichter in that Trump is not a conservative (maybe out of ignorance and lack of exposure more than anything else), but do agree that fighting back is necessary, and even if Trump doesn't know the 9th Amendment from both Corinthians, he is at least fighting back and supporting a conservative agenda, even if he is doing so sort of instinctively and not because he understands conservatism. His bobbles and errors reveal the lack of depth of his understanding, but I do think he's learning and learning quickly.
Do I think he will ever become a true conservative? No, but he is fighting and moving the doomsday clock a bit back to the right. It's up to conservatives to take up the fight....if we really think it is worth fighting. If not, we can just stick to our keyboards and argue amongst ourselves as to who is the most orthodox and who are the heretics.
