Let’s turn this into a non-Hypothetical. When I go to my in-laws house, my father-in-law wants to talk politics from time to time. He’s a retired teacher, head of his union local that led his union to strike, twice, ten years apart. Needless to say, he an I don’t agree on much and on a few things we disagree to our very cores. He has enough love for me and I have enough love for him not to attack him personally and express myself in a respectful way.
If I were to express my dislike of Newt in a way that was deceitful or in a way that was disrespectful to other conservatives, that would be wrong.
If you want to duck it, fine.
In this non hypothetical on FR the equivalent to your FIL told you at the door today that bashing Newt and any other conservative was now off limits.
So do you
A: Follow his direction:
B: Bash anyway / argue with him about it since that’s your expression of opinion
C: Say “OK see ya” and leave?
Because that’s exactly the choice you have here and you claim B is perfectly acceptable when it morally/ethically/and in decency/respect it is not.
