It’s not pretentious to think that people who have no background or experience in a subject should not pretend to have expertise in that subject.
The ease of publishing thanks to the internet has made idiots like you think their writing has value (it doesn’t). In feudal times, you would be a starving peasant begging your local lord (someone like me, that is) for your daily bread serving. (Hint: you’d go hungry today for running that mouth).
Update:
Statistically, it’s very likely that I’m richer, smarter, and taller than you.
You confuse pretentiousness with genuine (genetic) superiority.
And
I don’t have a job, as you implied.
But, to be fair, that’s because I’m rich (see previous points).
Members of the capitalist class, like myself, find fulfillment in exploiting the labor and bodies of the unwashed/untouchables (e.g., you and your family).
Society would be better if you were forced to address me by a proper title.
