My reasoning was that those most affected by NN repeal and potential loss of access (slow access) are those who would not be able to afford ISP price increases for what most reasonable people would consider open and equal Internet access comparable to Internet for people with more means.
This would effectively discriminate against a significant percentage of the population would it not? And put them at further disadvantage.
This sounds like "world ends, poor people hardest hit". Of course, any price increase would affect poor people, but that's not how "discrimination" works - you can't just claim that anything that increases the price of any good is "discriminatory" (otherwise we couldn't have most of regulations, since many of them do increase costs, whatever are their other perceived or real benefits).
And, "poor people" are not enumerated there anyway - it's "on the basis of race, color, religion, national origin, or sex". You could of course claim that since there's more poor people among, say, blacks than whites, it's related to race, but that would extend "discrimination" way beyond point of any usability - you could then claim that producing and selling any expensive good is racist, which is insane.
