I have not made such an assumption.

The statements in context are referring to a potential future time when they say that it's not offensive. I made no statements about what has, or has not been said currently by those groups. I only acknowledged that currently the word is considered offensive.

I recognized in my original reply that the wording of the picture in the OP is problematic. Though it carries a decent enough message, the wording would be considered offensive by today's standards.
