One thing about forums is the inability to read body language, tone, etc like you would normally do when conversing face to face. I've seen a lot of post taken the wrong way.
If you want to be part of a cycling community, help each other, learn from others, etc you should learn to ignore what might be an offensive post and most of the time the poster did not mean to offend anyone at all. These misunderstandings could be avoided by asking a follow up questions just to be clear what was meant and understand right or wrong we all have our own opinions.
That being said if it was an all out, singled out attack I am all for defending or stand by what you believe in.
