Well one glaring error is that they speak of the 'LGBT' community, not the trans community, and quote stats that do not refer specifically to trans people:
Research shows LGBT people are more likely to find themselves homeless than their non-LGBT peers, and make up around 24% of the youth homelessness population. Here at Centrepoint, we are fully aware of the need to provide safe spaces for this community.
Statements like this make no sense as LGB people and T people are not one community, they are different, have different needs and un-differentiated services for 'LGBT people' will probably result in males in female spaces and vice versa.
LGB✂T isn't just a slogan for a slogan's sake, it's the only way to make sure appropriate services are delivered to specific groups, such as LGB and T, but not in one artificially bolted-together 'community'.
