Hypothetical:
I go into your house, express my poinion that your wife needs a diet and hit on your teenage daughter. Do you feel it’s acceptable for me to express my opinion in your house? Because “I’ll do it if I want to?”
Yes or no.
Is it ‘right”?
Yes or no.
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.
