You share with the generous hearted( and generous with my taxes) idiots ( whom you misrepresent as the Left) a refusal to grapple with reality : the potential millions moving on Europe come from failing states from around the world- Syria, Iraq, Afghanistan, Libya – and through the latter, from Nigeria, Eritrea and others. None of these failing states, nor many others in Asia, Africa, the Middle East adjusted to the doubling or more of their population since the 1960s, the world’s population growing from roughly 3 to 7 billion over these five decades.
As the vast majority of the millions of migrants on the march word wide are young males without particular skills, and do not they share Western culture and principles, can suspend your moral preaching for a moments reflection to ponder the question of consequences

I had to rub my eyes: the author is accusing people of personal morality? is righteousness a crime?

Doing the right thing is always superior to getting a desirable outcome and the means are at least as important as the ends.

With some good points, the author could well and probably successfully argue the immorality of the actions of her political opponents, but blaming them instead for being moral is her knock-out.

Hound,

We all know by now that this 'straw man' rubbish is your way of dealing with those with whom you disagree. Time for a new slogan or sensible argument.

The road to Perdition(hell) is paved with good intentions

So goes the old saying.

This author is making the point that a lot of people are
More interested in their own sense of do-gooderness, than
In seeing the enormous negative results.

For instance how many people would be so keen to
Share their home with 5 refugee families and have the economic
Burden of feeding and paying for all their needs.

In this sense their moral self righteous behaviour is only a surface warm and
Fuzzy feeling for them.
They can be so generous because they themselves personally don't really
Have to pay or sacrifice anything,.
Different story if they were told by the government that every Australian family
Had to share their home and money with two or three refugee families.

Yup,

1200 or more people were killed by the greens good intentions, and thousands more are dying on the Mediterranean .
