I feel like the correct answer to the above questions are:

"Yes, I don't my children to be taught about racism, sexism, feminism and slavery". "Yes, racism and sexism does not exist. Stop teaching it".

Then wait for the name calling.

If teachers were to stop teaching the above, you as a parent can still teach your kids those bits that weren't covered in school. I am pretty sure you'd do a better job.
