A Christian Reaching Out For Honest Conversation With Muslims

Salam alaikum, peace be upon you. This isn’t a request for private messages. A while back I tried speaking with a Muslim online to ask some questions, which went well enough, but the chat system had issues and our talk faded out. I've been told my whole life that Islam is evil and promotes hatred, even hearing terrible things about Prophet Muhammad ﷺ - though out of respect I won’t repeat them. I’d love to connect with practicing Muslims to learn about your faith firsthand. Where should we start? If anyone is open to chatting, I’d appreciate it – though fair warning, my replies might be slow. I’m working 80 hours over six days right now and completely drained. And heads up: I’m pretty ADHD and socially awkward, so if my questions come across too direct or blunt, please know I don’t mean offense. Just kindly let me know if something feels off, and I’ll respond with respect. To begin with… why do so many Christians believe Islam is satanic or anti-Christian? I genuinely want to understand.
