Truth be told, I no longer identify with a number of claims, conclusions and views in some of my older texts. The rule of thumb #1 is - the older the text, the greater the likelihood of my present self disagreeing with the opinions I held in the past. The rule of thumb #2 - if it it has an air of "liberal consensus" to it, it's outdated.
There is nothing embarrassing about a gradual process of getting mature. The opposite would be embarrassing. Nonetheless, I decided to keep all the texts on my website. They stand as a testimony of my writing skills.
