I don’t want to make wearing heels socially unacceptable.

If you feel that you, personally, don’t look professional without heels, go ahead and wear them with awareness of the risks.
But bluntly, what women who literally can’t wear heels are “resenting” is being discriminated against for something that can’t be changed. Like a disability.
If you acknowledge that not being able to wear heels is not a choice, then you are in favor of discrimination.
