Nonsense. You are making the assumption that laughing is always voluntary, and only to communicate that you find something amusing. Both parts of that are false - for example many people will laugh instinctively as part of a fight flight response when the perceive danger from others to communicate "hey im with you and not scared, don't hurt me more". People who hate veing tickled because they feel defenseless will still laugh when tickled, for one concrete specific.
You must be one of those people who have decided they're charming and funny, without realizing that people only chuckle at your "jokes" because they are worried about what you'll do when they tell you to stop making them uncomfortable.
