Obviously not; is is a community of faith that has produced and continues to produce good fruit, even though some of its members, and especially its leaders seem to spend more time protesting what they don't understand rather than sustaining the deposit of faith that has not been violated by Luther and his followers.
At the same time, Protestantism is a form of institutionalized anticlericalism as it denies most elements of the Church: priesthood, sacrametality and historicity. You should not feel slighted when your ecclesiological philosophy is taken seriously enough not to call your communities Church.
It is of course, common and unobjectionable parlance to refer to the Protestant houses of worship as churches.
I would agree -- guardedly. While there are many good Christian individuals in the Protestant groups (and many in this forum), the groups would not be part of The Church in any sense.
