Even MORE secure than FF.

That doesn't explain the fact that IE uses a lot of CSS that isn't exactly considered valid or accepted by the standards

Believe it or not, vB was supposed to be used with IE, if you want the extra stuff working.
Try editing the templates in your ACP on Firefox, now look at the same page in IE. You get the picture...

This rather means that vB is (partly) coded poor; if you write decent code/markup it's supposed to work in the majority of the browsers, making your site only for one narrows your group of potential members and can thus be considered as not the best thing to do.

Statistics have shown that roughly 10-30+% (Depends on what country/target you're aiming) of the users on the web are using other browsers than IE, which is quite a big group in fact.
