Do you agree that his arguments are not logic and conclusive?In that they are public speaking and they are not a thesis. They are public speaking, and those aren't logical and conclusive. The point you're trying to make could only stand if all the speakers you like and feel represent your world view have 100% logically rigorous speeches.
But can you point out where he says it’s so great to be alive?
I don't need to, to refute your silly assertion that he's somehow anti-happiness. None of these videos are direct statements about joy, because they are from talks where he is making an entirely differnt point, but it's clear that he's like any human being who thinks children are wonderful, and likes to have fun and laugh.

3. If you call „I survived the gulag where thousands perished“ as a silver lining you must have a pretty grim world view.
Again, not what I said. You said that he put forward books to depress his audience. That's obviously not true. The Gulag Archipelago is meant to alarm and meant to make a personal, emotional connection to the magnitude of the possible evil of such flowery sounding utopian ideologies.
If you don’t find it depressing you must have a very strong character
Or, one could be sure that one is in opposition to such ideologies. My father's older brother disappeared due to one regime with a collectivist ideology. My family here in the US is only here because the US military defended their lives from another regime with a collectivist ideology. Why should The Gulag Archipelago make anyone depressed, as opposed to angry? As opposed to resolute in the opposition of disguised evil?
I can only imagine it makes someone depressed if they identify with such an ideology.
What's more, I explicitly cite Dr. Peterson's message, "As for a silver lining -- to buck up, bear your burdens, and strive to live a worthwhile life," as a silver lining. I find it problematic that you ignore that and try to stuff a different position in my mouth above.
