Because some things are scrollable and it’s usually fairly obvious if there’s going to be more content.

If it’s not clear to you, I totally get why you think that.

But I don’t suffer the same issue.

Why should I have to have scrolbars plastered all over the show to tell me that something is scrollable when I can check it myself in less than a second?

I understand why people disagree - why is it so hard for you to understand that I disagree?

Generally it feels like the pro scroll bar opinion is actually quite aggressive, needlessly so.
