I'm libertarian but I'm not against welfare. I think the current system in my country is broken but I'm not against a system where the state helps those who genuinely need assistance. That assistance though needs to come with a plan for those who are able to work to actually get what they need (education, job training, whatever) to start working.
Sorry there is nothing libertarian about the confiscation and redistribution of private property by the state under the threat of violence.
Don't take it the wrong way but if you can't realize the obvious logical fallacy then you are merely "libretarian" in name only. Because it is the "cool, edgy, nonconformist" shade of Republican.
You are assuming welfare funding has to be by force. If churches collect and spend voluntarily, I would still call this welfare. And as a libertarian, this is OK. Same can be said about "Foreign Aid", we all assume this is the government spending the people's money against their wishes. People from one country helping those of another voluntarily is still foreign aid.
