That is a strange interpretation.

According to you, a drawing equating a black person to a monkey is only problematic if some people do really believe that black persons are literally monkeys? And people who enjoy these drawing are lacking basic biology concepts and would be flabbergasted if they were told that, no, black people is not a different species as distant from white people than macaques or gorillas?

The problem is the message that it carries and how it unities, spreads and empowers racist communities.

"Don't feed the trolls" is a cute saying on the internet, usually said with confidence by people who think they are smart but in fact don't really know about what they are talking about. And the goal is usually to deter a troll from a forum, so they can go to the next one and do the same trolling (so, it does not stop any trolling, it just displaces it). And it is not even clear if it is working.

It is also quite a coward way to response to that. Imagine "oh, these people are beating a foreigner to death. I know what to do: just ignore them, they are doing that for the attention, if we ignore them, maybe they will stop". Trolls act for attention, but these trolls are getting plenty of attention, from racist communities that loves them (and often even manage to groom them). So, who care about "feeding the troll" or "the streisand effect", this has no impact of the damage they are doing.

> Nobody is complaining about trolls being told they are assholes.

In the comment I've answered, you were literally saying that the trolls were unfairly blamed in the same non-logical way one would blame Hindus for their usage of their symbol.
