I Hate Internet Explorer

I really do hate Internet Explorer and can't understand why Microsoft can meet Browser Standards like others do. I spent some hours this afternoon modifying CSS for my Church website and got everything how I wanted it to look for now only to find that IE6 and IE7 don't like the CSS so I have to spend more time to figure out how to fix the issues. I mean if Firefox, Safari, Camino, and Chrome all work why can't IE.
