So what? The house of Lords is a revising chamber, and the Lords Spiritual are precisely the sort of people who should be serving in it as currently constituted: people with experience of governance but whose life experience includes dealing with real people in extremis.
if we are looking for people with this kind of life experience, why not just find them? Why restrict yourself to this particular group? I am not saying that we should bar bishops from the house, just not reserve seats for them. In fact, if more are qualified, we should have more.
That's the point. Qualifications over title, something that's often lost on this country.
They have voted, and spoken, generally progressively and thoughtfully and are widely respected. They represent less than 3% of the membership of the House of Lords and do a pretty good job compared to the other 97%, and I don't see why serving bishops should be any more dubious than ex-ministers, rich donors and so on (the hereditary peers are of homeopathic importance these days).
I never criticized their record, nor claimed they were more dubious than ex-ministers. Certainly, in reforming the lords, the spiritual may not be the most that's wrong with it. But the problem of religious exceptions goes well beyond the lords (the discrimination in schools being a big one), and it all needs to stop.
It's interesting that this post seems to contradict your other post from 08/10 12:44. In that post, your essential claims are that these Lords are completely inconsequential (so why have them?), don't change decisions (true for any group of this size) and vote progressively (completely irrelevant), but in this post they same absolutely essential (vote thoughtfully, vote well). Well, which is it? As I said, I don't think the spiritual is where I'd start for reform, but would be part of it.
Your other claim that they wouldn't vote in block for fear of a backslash is more worrying. Why are they not voting with their conscience? Why shouldn't they vote as a block? Because their role as bishops appointed to the House is precisely what's hampering them. In effect, they render those seats less useful for fear of a backlash.
It's all similar to all the arguments you hear about the monarchy (which does in fact cost a huge ton of money). They aren't harmful seems to be their major selling point. Well, that just isn't good enough, or more precisely shouldn't be good enough, for positions of importance and prestige.
There isn't currently a proposal for an elected House of Lords on the table that looks like anything other than stitch-up by its proposers, so we're left with the current system working reasonably well with an entirely irrational basis, rather than moving to a more rational system which would work badly (the US Senate is hardly a reassuring model).
The US Senate is also the deliberative chamber and has enormous power. It functions even though having 1/8 the size for a country 5 times as big. Members voting patterns aren't affected because of their perceived illegitimate route to the senate. Senators have to earn their seat at the ballot box, rather than just having a chum in government.
