This unfortunately is quite a complex matter. The Church of England is also the Anglican Church across many other countries and cultures.
Those other countries congregations do count when making top-level policy decisions like these.
At individual church level, some are more Liberal than others, after all its a broad church made up of different local communities and congregations.
I think it is good Archbishop Justin Welby met with her. But, when will she meet with the Chief Rabbi or Imam, for talks.
They all know things are changing, but religion based on beliefs and written works can only ever change so slowly. Look, at how long it took us to get women priests. And it's sad to say some more old-fashioned/extra traditional members don't like. Whereas, at at least 8/10 don't care. In most churches all are welcome, there is no questionnaire at the door.
It is unfair to label all Christians as unkind.... we are all just individuals, some nicer or more generous with their time than others. We are no better or worse than anyone else, we make bad and good choices, have bad and good days and some even swear. Some are not so nice, but, we are all human.
But, most of us believe in God and Jesus Christ, and that faith keeps us going, even when the world seems against us.
