I think you need to ask yourself why should this country accept the influx of largely young male illegal immigrants who are being allowed to stay here at considerable expense to the taxpayer. Also often overlooked is the fact that by arriving announced and without authority they leap frog those applying to come here for genuine reasons and who have gone through the proper channels.
The government is selling this proposal on the basis that it will deter people from risking their lives crossing a busy waterway. It won't do that, but even if it did, that should not be their primary concern. Their main aim should be to stop the resources of this country being plundered by people with no leave to land here at the detriment of those already here.
So if you are interested in morality, consider whether it is moral for the government to spend £1.8bn a year on hotel accommodation for these people when the country is in such a parlous financial state and the population is currently being taxed at one of the highest rates in history. Also bear in mind that, unlike the people in Ukraine, those setting out in rubber boats from Northern France are in no immediate danger of peril. They simply don't like it where they've made their way to. As always, there's two lots of morals but unfortunately one seems to be trumping the other at every turn.
