Rick - aha, I think I have now understood your sentence about the demonisation of private landlords:
"I also saw the demonisation of private landlords as the cause of the high rents charged".
I interpreted this to mean that in your opinion it was the demonisation of private landlords that was responsible for the high rents being charged in the private rented sector.
I now believe that what you MEANT to say was that the high rents being charged in the private rental sector are resulting in the demonisation of private landlords - no?
In that case, I absolutely agree with you, and the use of the word "demonise" in that context would be justified. Not all private landlords are evil, of course, but some clearly are - particularly Buy-To-Let investors who deliberately set out to exploit the housing market for personal gain and in reality end up making their profits by exploiting people.
