“Turning it into a commentary on slavery is dishonest”
I don’t know who you think ever said that.
Wake up. Everybody says that. Virtually every reference you will ever find to "all men are created equal" will be in the context of slavery. Virtually no one speaks of it regarding the actual intent of the Declaration, which is to justify why 13 states wanted to separate from England.
People are constantly conflating the Declaration with anti-slavery, and this is just wrong historically.
