The religious of this country of all religions are split between not having bishops in and having bishops in. I have heard it reported on the BBC that people of other faiths are glad that there is some spiritual involvement in government and that it has allayed the kind of fear among the religious in countries such as France.
Oh don't you just love hearsay being used as 'evidence'.
To assess public opinion on this you need proper polling. Admittedly this hasn't been done often but there is some actual evidence, which shows:
1. Overall the public is strongly against Bishops in the House of Lords - typically more that twice as many don't support their presence as do support their presence.
2. Unsurprisingly the non religious are most against.
3. More surprisingly, ICM research for the Joseph Rowntree Reform Trust found that more religious people did not support their presence than did.
4. Most surprisingly Christians were also against their presence, with 48% not supportive compared to only 33% who supported.
But hey why bother with evidence when hearsay, anecdote and 'I heard a guy on the BBC once say' will do.
