I have no idea what your target demographic is, so please, take my advice with many grains of salt.
If your audience is pursauded by arguments from Justice/Rights, then you’re doing well. If your audience is pursauded by arguments from utility, then you are lacking. Most socialists are afraid that without government, there would be rampant poverty, racism, and inequality. Even most moderate supporters of government intervention are usually in favor of the minimum wage and anti discriminatory laws. They don’t realize the consequences of these policies actually hurt the very people they are trying to protect. If you have a particular issue in mind, try looking it up in the mises.org daily articles. They cover just about every issue under the sun.
But instead of just telling socialists that their plans are wrong, you might consider trying to accomdate them within the market. For example, state-enforced universal healthcare is not compatible with the free market, but a voluntary pooling of resources for healthcare is. See this link for the way that healthcare used to be provided in the United States until it was taken over by the government. I’m sorry I can’t find a Canada example, but I am sure you have something similar to our AMA.They may claim that they need to steal the rich people’s money to have better healthcare, but once the argument gets to this point, you already have the moral high ground (in most people’s eyes)
For more general statistics, this thread has some great graphs/tables. Sorry, again I think it is American. But if you like what you see you might be able to go pull up the same data for Canada.
Anyway, thank you for dedicating your time and energy improving civilization! Our best wishes to you. I’m sure you can find plenty of help on these forums.
