First part of the post is not being serious as indicated verbatim. “Not being serious”

At the end it’s followed up by “on a serious note”. So that very last part is serious

No, suggestions to tell these people that they lack comprehension was not serious. I am not an idiot. If they lack comprehension, it doesn’t mean one needs to point it out. It was clearly stated that it’s not serious. The only serious part is the end of the post.

Sometimes all one needs to do is read twice to make sure. Kindly reread my post. Then kindly back off. Criticizing other people’s posts especially if you misunderstand them, serves no purpose and isn’t supportive for OP.
