If you don't agree with not being able to post what you like (whether it be harsh or what have you) you should take it up with the eHealth administration. They make the rules - and we're expected to follow them. These are the terms required to continue being part of this community, and if you have an issue with them, you should either tell admin or consider leaving eHealth.
eHealth is a forum specifically designed to help and support, NOT to put others down or make them feel foolish. If somebody is posting something you don't agree with or find ridiculous, either ignore them, tell a mod, or try to give helpful constructive advice without being rude or mean.
Again, you can pm admin or a mod if you have any issues with this.
