Well, my assumptions are based on tangible proof.
Then cite that tangible proof (also, if you actually had tangible proof, you wouldn't need to make assumptions--you'd have facts).
There as many students here as there are writers.
That statement needs a lot of clarification. If you mean that the total number of students that have ever posted on this forum is equal to the number of writers, then probably (although you're still making a statement of fact without any actual proof). Most customers that post here don't do so more than a handful of times, though, while most writers stick around for at least a few weeks. The number of posts made by writers and other people that work in the industry vastly outstrips the number of posts made by students, especially because of threads like these.
It is obvious that since you are among the "Top 5 high-volume posters", a good number of your postings are directed to students!
That isn't obvious at all. While it is true that a number of my comments are addressed to students, the vast majority of them (for reasons described above) are not.
