I have no idea why you think like that, although you are in good company here. This section of the site is full of such warped thinking.
No one in their right mind would welcome any kind of institution of that sort opening up on their doorstep, so to suggest I would be a “big fan” is malicious nonsense. I wouldn’t be.
That though is entirely different to understanding and respecting the need for our country to have to deal with the realities of a situation none of us want. We have obligations under international treaties. People make asylum claims that take time to process. Our means of doing so is overwhelmed so delays occur. We don't yet have enough purpose built facilities to house those needing to be housed.
Those who suggest simplistic solutions are misleading people irresponsibly. There aren’t any such solutions. The only way to overcome this is the long hard slog we are involved in, which is, very slowly, working. In the meantime some will get discomforted. It might be me, although practically I see no actual chance of that happening as nothing remotely suitable exists locally.
How we manage such facilities is an entirely different matter. Unless families are involved I see no reason why those being housed are permitted to roam in communities. I am not any kind of expert on the logistics and manpower required but secure facilities, well away from urban centres, with basic work expected in return for accommodation, seem sensible to me. They aren’t here on holiday. Keeping them safe and fed is all we should be doing. Alongside ensuring our lives are disrupted as little as possible. I see some signs of attempts to do this.
