So my mum is pretty great. She's a really damn nice woman, to the point she'll do just about everything she can for me and my brother with no thought of reward. She even tried to insist on splitting the cost of, if not outright paying for, a birthday gift we got for her. She works damn hard in an unforgiving job with a bunch of arseholes that do nothing but criticize her at every opportunity, all while continuing to keep house and other responsibilities. But even she has her flaws. She fervently believes there is a Muslim conspiracy (hence the title~) to take over the world. Every once and a while, we have just about exactly the same debate over whether there really is a Muslim conspiracy, usually prompted by a news story or some other such rot. Every time, it starts with her making some assertion that Muslim people all want to dominate other countries by migrating into them and eventually becoming the dominant culture by forcing others out yada yada etc etc. You've probably heard this before. Me and my brother, we try to make the obvious argument that she has no proof of this conspiracy, and that she cannot possibly claim that all Muslim people are simply tools in some great war against the West. She makes some feeble attempts to justify her position by pointing to ISIS or Saudi Arabia and saying that they represent all Muslims, or at least the core of their beliefs. This continues in a circular fashion for some time. Now, her beliefs are one thing, but the worst part is how she treats these discussions. She usually shuts them down by claiming she's tired (which she probably is, but it's besides the point), that we're attacking her, making her the enemy or something along those lines. And then all this is forgotten for the NEXT time she feels like making ridiculous assertions like this. We can try and reason with her all we like, but all we ever accomplish is getting the conversation shut down faster than usual. This isn't limited to Islam either, but that just seems to be the topic of choice lately. So, my question is; what on earth am I supposed to do?
