I find comments are made much better (are more likely to influence someone’s thoughts) by just deleting these parts.
Try to communicate out of a desire to learn first, inform second, and just skip the shaming.
I believe I made a point that is relevant and that has also been discussed in the media this year. A condescending attempt to dismiss it is poor form.
Lines like this make some people prone to just dismissing what you have to say because you come off as anti-US, anti-Western, pro-communist, or whatever they perceive that line to imply. It also looks like you are virtue-signaling to people who already share your point of view.
Something I often hear at work about me that is valid here is "People rarely disagree with what you say but they disagree strongly with HOW you say it".
We both may wish people didn't care about the "how" if the "what" is correct but that's not the world we live in.
