Regardless of political affiliation—left, right, moderate, far-right, or far-left—you must not fabricate information

You can use harsh language, but there should be a line
You can talk nonsense, but don't try to destroy someone through fabrication
Don't label people without evidence
And don't act like "I'm the one who posted it, so I'm the expert"
If your hobby is just labeling people, fine
But fabricating posts and making up things that never happened
Is a different matter entirely. Go write an apology letter.
