Well, aren’t you just the compassionate one. Some homeless people choose to be in that situation, plenty don’t. It may be financial circumstances, not just alcohol and drugs, or many end up on the streets because of domestic violence.
“Poor naked wretches, whereso'er you are,
That bide the pelting of this pitiless storm,
How shall your houseless heads and unfed sides,
Your loop'd and window'd raggedness, defend you
From seasons such as these? O, I have ta'en
Too little care of this! Take physic, pomp;
Expose thyself to feel what wretches feel,
That thou mayst shake the superflux to them,
And show the heavens more just.”
However, people like you who advocate such violence and genocide are an easier problem to deal with than homelessness. All it would take is one bullet - just as you advocate for others.
