That's correct. For some crimes a fine, a community service order, or other punishment may be appropriate. I don't think you are seriously arguing for the imprisonment of people parking illegally are you?

People on remand already have the right to vote (innocent until proven guilty) so it is not impossible for prisons to organise postal votes for prisoners who wish to vote, and participating in the country's democratic process may help rehabilitate some prisoners.

Of course some people are just scum and don't deserve the right to vote, not all of them in prison. But this does not excuse society taking away their right to vote which should be allowed as universal as practically possible (including for young people above the age of 16). I don't accept the argument that denying prisoners the right to vote will act as a deterrent or punishment, you might as well argue that they should lose their right to wear matching socks.

I would be happy for voting right to be taken away from prisoners who have taken away another person's right to vote - those convicted of murder and election fraud.

If it is good enough for Australia, Canada, the Czech Republic, Denmark, France, Germany, Israel, Japan, Kenya, Netherlands, Norway, Peru, Poland, Romania, Serbia, Sweden and Zimbabwe, then it should be possible to achieve in the UK.
