If it's on your channel even though It looks bad, the more people are commenting the more views your video is ganna get. Since people see that there are more comments on a video it can also draw them in cause they see the video is interesting enough for people to comment on. Obviously if someone is being rude or just an ******* on the comments just mark them as spam or blacklist them if it comes to that. As long as people are sharing their opinions even if they are aggressive (comment section is always toxic) then leave it, it's good for your video. A lot of YouTubers spoke out about their comment section, some have disabled them because they can't deal with it but the general rule is to leave it alone unless it's some sort of discussion video that you can partake in. The people who get really annoyed because of a conflicting opinion are the people that shouldn't be allowed to comment, it's just stupid since there is always someone who will not agree with you and that's fine cause it's life.
