The 'LGB Alliance' is a hate group. It was set up purely to agitate against the rights and dignity of trans people and to drive them from the LGBTQ movement. If people promote bigotry against L, G, B, T or Q people in LGBTQ spaces, they should expect to be asked to leave.
As it happens the 'LGB Alliance' is completely marginal to the LGBTQ movement, it is anathema to the vast majority of LGBTQ people, and is being cheered and promoted by bigoted people who aren't even LGBTQ. Their bigotry and their aims will be defeated, and they know it.
Also: like most bigots, the anti-trans cult are the most awful crybullies. They have the support of most of the press and constantly try to get their opponents fired, but claim they're being silenced, and loudly promote their bigotry and cry victim when it's challenged.
