I can't down vote your comment, but if I could, I would. It isn't constructive to the conversation at hand.

But on a personal note, if you can't find interesting, intelligent content on Reddit, that is a criticism of yourself, not Reddit. Reddit houses some fascinatingly talented, smart, engaging people across a vast array of subject matter.

In order to find that interesting content, you need to learn about it. I can imagine many new users coming to reddit, seeing just the front page and drawing their conclusions, turning around and not look back.

Should they be criticized by that?

Maybe take the time to share some of that interesting content here to parent to change his view instead of denouncing him. (https://xkcd.com/1053/)

I upvoted your comment because it's so constructive, telling me I'm an idiot because I don't find reddit interesting.

That does seem to be the owners' plan going forward.

The type of content that Reddit's design encourages most would be meme-blogging in the style of r/me_IRL
