I have yet to meet a church that is unwilling to share the space with others who may find spiritual comfort
Some have to be locked at times because of the high danger of vandalism, theft or desacration, but most are open all day for anyone who wants to visit. Church visiting is a family obsession and I have never been made to feel unwelcome anywhere.
When pews are removed it is usually, to make the church more flexible and welcoming, to enable it to hold concerts and theatre events, to hold social events and provide a welcome ministry for everybody.
There is a difference between a church welcoming visitors, who wander in, walk round vaguely and walk out and make no contribution to the upkeep of the building that is helping them pass their leisure hours in a pleasant way and a church that wants to be a social hub to the community it serves. You cannot run amother and toddler group in a church with pews.
Some churches do have church halls and the like, but not all. These are the ones most likely to keep their pews, but pews are merely furniture tat help a church meet its real purpose to life and if they come between the church community and its mission they are expendable.
