Trans-Stratification

I was recently at a meeting to discuss how the needs of the transgender community in the state of Maine should be addressed over the upcoming years. While a nice big list of needs was created which covered everything from medical to safety to family needs, there was also a "dirty laundry" list. Well, it wasn't actually written out- just aired out, if you will.
Here's the issue: basically, one woman quite passionately expressed that she feels that someone identifying as a crossdresser should not have as much right to identify that way as someone who identified as transsexual and had been in transition for 13 years, such as the woman who was voicing this opinion. She felt that the transgender umbrella should only extend its welcoming protection to those who were "serious" about changing genders and not to those who "only do it in weekends in hotel rooms for sexual pleasure". (A view which misses the purpose of crossdressing.) 
So here's the question: is one persons right to express their gender however and whenever they please less than someone else's right to express their gender? 
It's funny, all this time I thought that any action that challenged the constrictions of gender was good for us all- transsexual and crossdresser alike.
