Comments not being posted

I have been commenting on a number of news articles, including one regarding the House moving on impeachment inquiry. There are a number of people that are posting claims that I believe are not true or of sound logic. However, when I post what I believe to be a respectful response questioning those claims, and a few of my comments are posting. 

I would like to know why my comments are not being posted, and if I am being censored, what exactly is the policy that I stepped on that would cause you to not post my comment without informing of your action? 

Or is it a bug in your system? Which is it?
