If you want people to take you seriously, try behaving in an adult manner. “Bite me” is a childish and uncharitable phrase. Some could consider it a personal attack. Plus, it pretty much makes you sound like a child, and detracts from any message you may wish to convey.
I believe that it is against forum rules to question the professed faith of anyone. Including posters who have differing opinions or even Nancy Pelosi. It is especially uncharitable to infer that anyone should leave the Church. You are not perfect, I am not perfect, no Catholic is perfect. We all have issues.
While many of us may not agree with Pelosi or Biden, we still have the responsibility to treat everyone with charity and respect. The Church demands that of us. Lets try our best to keep these discussions on a respectful level.
