Abba_S:
1. They posted your comment despite the fact that it was Motzi Shem Ra, so you can’t claim media bias (at least not in the direction that you want to claim it.)
2. They also posted your above post even though it contains sheker about the Torah (as explained in #3).
3. Regarding point B, this is completely false. The halacha is that something is considered Motzi Shem Ra unless it is CLEARLY TRUE. You are not allowed to say anything negative about someone unless you know that it is definitely true. You had stated in your original post that the guy was not dating for marriage. You DO NOT know that; hence, it is motzi shem ra. I provided the source for this Halacha above. You do not have a source for your statement.
4. Regarding point a, I already pointed out to you that there is at least one person who knows who the guy is.
5. There is absolutely no source for point c.
