That's per se. I wouldn't normally say anything at all, but the irony is towering over me, due to the topic/nature of this thread and the fact you've used a homophone that doesn't really exist.
Per se is Latin and means, "in and of itself" or "intrinsically".
I disagree; that's not the case at all, and it's a sweeping generalization that doesn't really apply. I've studied language all of my life, nearly 30 years in total after graduating high school, as an adult including college and independent study. I understand your point. However, I also think that evolution of language is quite beautiful, and the way this evolution occurs is via errors in grammar and communication. Those lead to pidgin and patois, which in turn can become new dialects.
You, yourself, made a grammatical error, yet I can see you both care about language and have learned something about it. I hope you can take that onboard.
On a tangent, did you know people said and used "aks" for much longer than we have been saying "ask"? Common errors can actually become the norm if repeated often enough. ... Eh, I digress, now I'm getting into Metathesis. Another topic for another time.
As for homophones, you can take an entire class in how misconstrued or incorrect homophone usage has given birth to some of the most interesting communication we have as humans. You do realize puns started this way, right? Had we never misconstrued homophones (intentionally or otherwise), many aspects of comedic communication simply wouldn't exist.
Language would be tres boring if every grammatical rule were followed 100% of the time. I promise you.
