i agree with u about home schooling.
i went to a public school (state school), had very few friends and was bullied a lot (i had problems socialising due to the way i developed).
and i am very very glad i went through that experience as it left me very close to God (my only true friend through all the trials of life).
also if i had stayed home, my social problems would have been much much worse and i would not have coped at all with going to university.
as it was, i finished my degree well, and had a good career (until now, i am not yet retired!)
so if u r home schooling to 'protect' yr kid, then don't!
we all (kids and adults) need to learn to deal with trouble in life and to call on God. the most famous saints went through loads of persecutions and have amazing rewards from God as a result.
are u trying to take away yr kids' reward in heaven?
so train them well in the way they should go (i mean a good few years at home, don't pack them off to nursery at 1 1/2 years!) and fill them with confidence that they are important and respect themselves and other people and then work through all the problems of life with them then they will cope well with whatever happens at school.
but if u r home schooling for another reason, maybe it's a good thing. i just think it's bad for society as a whole, and the people out there who don't know God need to meet us at school (if we're kids or teachers), at the school gate, at the school fete etc.
like if u really have to home school, maybe invite over the kids of your neighbour who is not Christian, so they can benefit too.
don't keep all the good stuff to yourself!
oh, and about the original topic (so i don't get told off...)
if any church is marginalising people, they all need a good slap.
but don't think for a second that's a 'protestant' thing, its a universal human trait that God wants us to resist!
