Thank you for your thoughts, AntRuhi. They're well-appreciated.
Speaking from experience as a professional in the world of dating and matchmaking, I think relationships with toxic people —that counts attractive people with toxic traits, can only deteriorate the mental health of the parties involved. If there's going to be a category for that in dating platforms and services, not only will that result in a lot of failed relationships, but I also think that will further lessen the value of love and relationship altogether, especially in the eyes of the younger generation.
