Nobody is saying you have to, if IE works fine for you, then so be it.
What's being said is that IE is less secure than FF, which, for a lot of people have discovered first-hand by getting a load of spyware/malware etc. After they made the switch to Firefox, no more problems!
If you haven't had any problems with IE, good job, but for those that have had problems, they are entitled to voice their opinions on IE, just like you can voice your opinion on Firefox.

Hmm, I never knew that, i'll be looking out for a few IE8 beta's now.
