Nalfein,
The gist of the removed post is similar to your most recent post, but with much harsher terms. While I agree in principle with many of the points that you made in both posts (and I posted similar sentiments) the tone of the removed post was more viscious. A Moderator deemed it as a personal attack and chose to remove it. When you reposted the same basic ideas in your most recent post without the same level of attack, it will probably be allowed to stay. Clearly on your second attempt you found a way to express your opinions without attacking anyone else. In fact, you stated some of your thoughts quite well, and provided good advice.
Please try to remember that the Mods are all unpaid volunteers, and they try very hard to be even-handed and fair. While you may not always agree with what they have done, they really are trying to keep the peace. Sometimes a post that has valid points, but just seems to be "fanning the flames" due to the tone or the choice of words will be modified or removed in an effort to keep things civil. I guarantee that you were not being singled out.
