Ok TheTexanYankee....
I am not one to make assumptions so the only way I can figure that you are part of the Greek community but that you have never gone through sorority rust at UT is:
1. You are in a Frat (In which case, you need to get back in your lane) or
2. You are in a sorority via transfer (In which case, you should really shut your piehole because you are not being very Panhellenic and ....well there is so much more but I will stop there)
3. You are in a Greek Letter organization such as a business frat or maybe in a sprint group that is governed by the Greek Life office (In which case, you are not only in the wrong lane, you are on the wrong interstate system)
Now with that said, Rush at UT can be a great experience for any young women who does her homework and is prepared. These young women cannot control the weather or who her fellow PNMs might be, but they sure can make sure their ducks are in a row, and that they enter the process with an open mind, etc., to maximize their chances.
As far as coming on here and talking about tier this and tier that, there are some Frats who limit their socialization with specific sororities, but frankly that is their close minded attitudes and certainly not the general attitude of 90% of all Greek members. (And bless your heart TTY...I suspect you are part of the 10%) As a matter of fact, those specific Frats are almost ridiculed for lack of a better term because it is really just ridiculous that in this day and time of UT Greek Life, that some people are so intent on holding onto stereotypes of decades past. But even these die hard groups have certainly opened up their social calendars more than ever before.
I will agree that at UT, when it comes to blending GDIs and Greeks at parties, the Greeks do stand out or maybe it would better to say the GDIs stand out because of basic sorority party attire. Most Friday and Saturday nights aside from the themed party or a formal night, most sororities represent in their letters and neon. This doesn't mean GDIs can't have a great time, it just means for the most part girls love to represent their houses and there is nothing wrong with that.
