There are many, many ways an individual may sabotage their own best interest. Some are obvious, and some of them are still brand new and not so obvious.

Here is my favorite, which is evidencing your own stupidity. Everyone who partake in "supporting Palestine" belongs in this category. However, if you are a homosexual or a female you created a brand new kinda stupid. This brand of stupidity did not exist before.

Its all evidenced, all documented, and all is hilarious.
