I can appreciate wariness toward the kind of tribalism you describe in your last paragraph, but in this case the BBC has actually acted irresponsibly, and you quoted one of the big reasons why from their own article:

The survey was not statistically valid since the respondents were self-selecting and Get The L Out is an active campaigning group on lesbian issues. But while Angela acknowledges the sample may not be representative of the wider lesbian community, she believes it was important to capture their "points of view and stories".

#1, Get the L Out is not "campaigning on lesbian issues," they're campaigning on anti-trans issues. Their stated aim is not to improve the social status and wellbeing of all lesbians or something, but rather to exclusively define lesbianism for all lesbians in such a way that excludes trans women, full stop. From their own website:

Lesbians are exclusively same-sex attracted.
Lesbians do not have penises.
Lesbians do not want to have sex with men who identify as trans-women.

Because of this, #2, the article is in no way and never was "a description of the problems within the queer community" (Get the L Out makes this helpfully clear in that the tagline of their group is "Lesbian not Queer." The article is, in the most generous interpretation, a description of a radical trans-exclusionary group's grievances deliberately obscured to masquerade as "problems within the queer community."

And #3, at least most of the respondents (to my recollection and again, self-selected from a group by definition pre-disposed to this grievance) had never felt direct pressure from a trans woman for sex, but rather felt pressure or fear of condemnation due to their own discomfort with trans acceptance.

There are actually many other issues with the article, and the BBC has dragged an anchor in making any corrections. I don't think this discredits them as a news source in general, but this and other examples do show a pattern of transphobia in the organization at large.
