This was your response to my suggestion that it was reasonable to be offended by boasters.
If one has a low self-esteem and dislikes anyone that appears to possess aptitude over others. We call these people "haters" in the conventional sense.
This has all the appearance of nonsense. I find boasting distasteful. In contrast I have no problem with persons having greater aptitude than I: admire them. But those who claim aptitudes they do not possess are an offensive to me and to others. This is not a matter of hate, it is a matter of rational distaste.
