Not acceptable within that person’s value system and virtues, which they’re signaling by calling it problematic. It’s an appeal to an imaginary Problematic Idea Authority that maintains a list of what people aren’t allowed to believe. When the commentary you dislike isn’t an exact fit for something readily indictable on the list, find something close that
is on the list (bonus points if it involves a controversial figure), reduce and compare what’s said to that, then proceed with shooting down the proxy opinion regardless of whether your read of what the person was saying is accurate. It doesn’t matter.
Read it again. That’s precisely what happened, followed by clicking the person’s profile to move on to fundamentally shaming the person rather than the problematic idea. That’s a standard playbook in 2021 and it is absolutely not at all about what was actually said. It’s a mating dance for those with similar belief structures and the person being disagreed with is a passenger; the response is only marginally addressing the speaker.
This community can’t get enough of that conflict because the microcosm of people it represents themselves cannot. So it does well here. Other people peacock it, and before you know it, it’s our defining culture. It’s how talking about culture without disparaging other cultures gets risky, because of the pattern matching mechanic against a black and white list with no acknowledgment of grays. “You talked about race, therefore you’re racist” is increasingly logical to folks, and once that chum is in the water whatever point you may have had no longer matters.
