> Please stop being rude to me.

I do not see how I was being rude, unless it was my use of quotations around the title you claim.

> I'm a human being ...

I did not doubt this.

> ... I'm a very experienced product manager and engineer ...

Again, if it was my use of quotations which you found to be rude, then I do not know what to say about that.

> ... and the way you are behaving sucks.

I respect your perspective and support your right to express yourself. And no, I do not think you are being rude by doing so.

> Assume I'm still right ...

Why would I? You responded to:

>> This is a site full of developers who are convinced that "proper software engineering" is 100% of what makes a business successful, and everything and everyone else is useless.

With:

> As a technical product manager, this 1000%.

Finally, you write:

> ... you might be able to learn something from someone else.

Maybe you can learn something from someone else as well.
