Don't get me wrong, I am no victim, over the years there have been a few on the left with multiple accounts that would comment several times to make their argument seem like it had merit, basically agreeing with themselves. Sentence structure, spelling errors etc gave them away. I actually felt sad for them. They still stop by now and again but once I hit them with facts over their emotional rants they leave again.
The votes up or down on my memes do not phase me at all, I enjoy a cup coffee, knock out a meme when something on the news catches my eye and I am off to enjoy my day. I do find myself checking later to see if someone commented. Usually, I make memes up on the spot, first thing in the morning. The errors tend to reflect my failure to finish a cup of coffee and wake up but that's how I do it.
I do enjoy discussions with people that do not hold my world view. I realize the sides are fixed and there will never be any conversions from right to left or left to right but we can still learn and seek common ground. Coming from a big family, I can have the discussions face to face any time.
I find meme discussions to short to really change minds but as long as people take the time to stop and comment, I feel an obligation to at least read it. Your visits are always a nice surprise, I think we have had several good interactions on all types of issues. You are right that there are plenty of people on all sides that just spew hate. I think we would both agree that will never change because as long as people hate themselves they will lash out, hurt people, hurt people.
Have a great day.
