Fine, kick the kids off. It’s better that way. Heaven forbid there be a place with both kinds of content. Imagine what would happen if bookstores or streaming services or years ago video rental places would do if they had all kinds of content. Oh and imagine that Steam had a filter to hide all that adult content wouldn’t that just be absolutely crazy?
Not everything has to be safe for kids. Kick them the fuck out if it’s an issue. Don’t dumb down the adults experience.
But what about the people who’ve got the maturity and responsibility of one, such as yourself?
Your analogy falls flat the moment your realize that G rated movies are served right beside R or unrated movies.
And steam has a filter to hide all adult content, and it also askes for your birthday all the damn time regardless of your account settings.
