That's a very black and white way of putting it. As long as you're an adult who can tell the difference between fantasy and reality, and you're not spending hours obsessed with it I don't think it's unhealthy. The way you phrase 'avoid it completely' makes it sound like you're going out of your way to avoid it already.
(I think the problems are coming through with the generation being 'brought up on porn', and thinking real sex is like it is in the videos online but that's a different story really.)
Definitely as a millennial I'm of the last generation that will remember arranging to meet up somewhere in advance and sticking to that plan (or rearranging over landline with more than a day's notice...)
But something I've noticed when I ask people in my team what their dream jobs are the younger people tend to say 'run their own businesses', 'work for themselves' etc. Whereas in our generation (in my circles anyway) that definitely wasn't so prominent. Maybe a side effect of seeing influencers making it big?
