For future reference: if I ask you to drop a subject or to stop talking to me for a period, and I warn you that continuing to press the issue will result in me blocking you, it is not a "threat" that you should feel afraid about; I am giving you necessary information to make informed decisions about your future interactions with me. I hold no illusions that anyone is "afraid" of no longer having contact with me or that it's even something worth fearing. Frankly, if someone is afraid of that, then I worry about their emotional stability. Nor is it because you have a difference of opinion. I am quite good friends with a lot of people who have radically different opinions to me, some positions to which I am actively opposed and even work against. The reason why they remain friends is because we both respect each others' right to hold those positions and not argue about them for the sake of peaceful interactions. I am opposed to the ideas themselves, not the people, and we can coexist, not just peacefully, but even amicably and as friends as long as a basic level of respect for each others' humanity is in place (if their opinion itself is a disrespect of others' humanity, well, that's a whole other can of worms).
No, when I tell you that I do not wish to discuss a topic anymore, it is not because of your opinion. It's because of your personality. It's because I find your approach to be disrespectful and I am attempting to keep the peace by just agreeing to disagree, at least for now.
If I warn you that I will block you, it is not because I can't handle differing opinions or that I live in an echo chamber. In fact, accusations of such are worth blocking for on that statement alone. It is because you are violating my boundaries in my request for peaceful disagreement and the only way I have to enforce my boundaries is to block you entirely because continued pressing of the issue is direct evidence that YOU DO NOT RESPECT BOUNDARIES and are therefore untrustworthy to be around.
I am posting this because I cannot message you after I have already blocked you to explain why you have just been blocked. So if you get blocked by me, this is why. It's not me, it's definitely you. It's not your opinion, it's you.
You are being blocked because you are untrustworthy, not because you hold a different opinion and certainly not because I can't "handle" that opinion, and not because I have to have to have the last word. In fact, there's a good chance that you already had the last word, since I will often not even bother to refute people I'm about to block, I just say "drop the subject or you will be blocked". You are not being censored (although I appreciate that you think I am a powerful enough person that I have the force of the government behind me, I simply do not have the ability to censor you). You are not more rational than I. You are not more level-headed than I. You are not more open-minded than I. You are entitled, rude, belligerent, pushy, manipulative, and a conversational terrorist*. None of that is more "rational" or "open-minded".
By the time I feel the need to resort to blocking you, I couldn't give a fuck about whatever opinion you think is so important that I'm blocking you over it. By that point, your opinion is the least objectionable part about you. By that point, I am more concerned with your total lack of empathy and your willingness to trod all over another person's request for space. If you can't even give that space on a stupid social media site, I have to wonder if I'm even safe being around you in person, or will I need one of the weapons that I carry on me at all times**?
And the internet is the ONLY place that I have the power to remove people like you from my presence. Every where else in the world, I am forced to coexist with people I am not safe around. Every where else in the world, I am smaller and less capable than those I am not safe around. But here, on the internet, I can force YOU to give me the space I need to feel safe.
So that is what I'm doing when I block you. I give fuck-all about your stupid opinion on whatever stupid subject that started this whole thing. I care that you have no consideration for the people around you. And THAT is why I will block you.
*Even for me that title is a little too hyperbolic, but that's what it's called and I didn't make up the term so that's the word we're stuck with.
**I have had to pull my knife on 3 occasions, only two of which were strangers but all 3 were people who did not back off when I repeatedly and clearly stated my desire for space.
