You do care, otherwise you would not even have thought about it twice, let alone comment.
The most striking argument against this line of reasoning is that there is no possibility for you not to act politically. By ignoring the issue of systemic discrimination (“don’t care don’t personally discriminate”) you actively contribute to and participate in the systemic discrimination.
It’s a choice, and I find it important to leave you the choice, as I do not believe forcing anything on you will actually make you see, but it is true nonetheless that you cannot escape your responsibility: The ability to respond. “You can not not communicate.” Not responding and deciding to remain ignorant about it is also a response, and a highly privileged one.
It would be easy to at least passively support anyone’s attempt at trying to reduce systemic discrimination, but speaking out against it turns it even more into a political act supporting discrimination than doing nothing and by that delegating it to others.
