In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: insult and non-insult. Insult is any lanugage or act that is disrespectful or scornfully abusive.
Q: Comment: I'm not one for engaging in semantics arguments, and frankly I'm not really clear on what lesbians do behind closed doors, but I suppose that things are done with their sex organs that do not involve penetration by a man.

I think most life scientists, such as myself, would get a good laugh out of your comment about "plumbing." It's like suggesting that a sword swallower's use of his esophagus is of equal value to eating.
A:
Non-insult
