I don't think anybody will downvote you just for making a point in favor of MongoDB, as long as it's valid.

If you are starting with things that are impossible to define (like the infamous phrase "internet scale") or are plain wrong, then you still don't have to shut up but maybe make sure you like your db of choice for the right reasons.

There are people who love mysql because they use PHP and others who love Mongo because they use nodejs. It's understandable: Those stacks have a lot of users and it's easier to get support. Nevertheless, it's not strictly a strong starting point when people are just discussing databases.

So, don't feel oppressed, just be clear with your reasoning.

I like to think of that as "personal blog with a couple visits a day".
