Though I think he needs to be convicted and imprisoned, I agree with you.
Don Lemon likely wanted to reclaim his name recognition and decided to drive towards the journalistic cliff- then actually go into the Church after he appeared to question himself as to whether he should actually enter it.
As a side note, following the Supreme Court's over turning of Roe v Wade there was spurt of protestors attempting to force their way into Catholic churches.
But.... my bet is that CNN and any other new service would have very quickly declined any invitations along the lines of: Hey, wanna have some newsies meet up with us for a "special protest mission", then follow us to a Church? (Uhhmmm, No!!- bye bye Hang up.)
Lemon was at CNN for 17 years. My bet is that CNN has never done anything remotely similar to the stunt Lemon pulled. Lemon would have known that. How desperate was he to re start his name?
