I would suggest considering that communication in general is one of the biggest challenges we have as a species. Text based communication is probably the most difficult as the medium misses several things that verbal communication has, such as tone, volume, and inflection. Things like sarcasm and opinions often come across as highly critical judgement to others with a different perspective.

I also suggest not ignoring or replying in anger. You can always clarify what you said and engage the person leaving a comment in a genuine discussion. If I get a comment that indicates that someone had an opinion or agenda and didn't actually get the point that I was trying to make, I'll reiterate my point and ask them questions that can either respond to or ignore. Leaving misinformation on a post that I feel detracts from my own reader's experience is something that I always challenge.

All of that being said, you personally have to be willing to consider that what you said didn't come across as intended or that you could potentially be wrong. Communication isn't a competition, it's a collaboration working towards mutual understanding. At least that is how I tend to approach things. If I'm putting out information or having a discussion, it's about opening a dialog, not telling everyone else that I know something that they don't or validating my own perspective.

That's the beautiful thing about an open forum, we can get other's input and perspective if they are willing to share it with us, there's no point in getting angry over that. Unless someone is blatantly trolling you or trying to derail the topic for malicious reasons, I highly suggest just clarifying your own stance and don't get angry at something that is likely just a breakdown in communication that can hopefully be overcome with more communication.
