If you google "Darren Blanchard activist", the screen lights up, TV, newspapers, etc. So, not his first time on the dance floor.

I'm not going to address whether what happened was completely right, or the merits of the underlying discussion. But this is not a case of a poor dirt farmer shocked at being arrested. I'd be very surprised myself if he didn't at least think that was a possible outcome (and would not presume to suggest that it was intended in any way whatsoever, obviously being arrested would be detrimental to his cause!).
