I identify as 100%, full-on, unflinching missionary, there’s no getting around it. This site wouldn’t exist if I weren’t. But I don’t shove it down people’s throats; there needs to be some curiousity to build on.
But I wonder if many of us are “unwitting” missionairies, as you both allude to. Meaning that if you’re asked about it, you answer and maybe sow a seed. If it’s a passing remark you make, it’s picked up by someone and it sows a seed. Or if they’re merely aware of your interest, they might seek it out and sow a seed (“Hey, if my friend likes this, I should at the very least investigate what it’s about!”).
