How ironic that you accuse me of abusing an argument/position regarding the abuse of the tool in question. A tool which is being used as a method by a lot of people who are more than willing to use against others to publicly shame and harass them.
Does this mean everyone misuses it? No, but a lot of people do and it is partially because of that which SE does not officially support it and is the same reason I do not. The argument I made was valid whether you like it or not. I actually like the idea of personal parser's but I do not like party wide ones because of the abuse I have seen frequently by those who use them. Am I biased in that I can only speak about what I have seen? Yes in the same way others might be biased in the other direction if they haven't seen it happen as much. Can I claim the majority of people abuse it? No, but I can without a doubt say a lot of people do because I have seen a lot of people doing so. Is it a useful and good tool in the right hands? Sure but in my experience it is quite often not used by people the right way.
It is a loaded gun which quite a lot of people are more than willing to fire at another to cause grief or because they lack emotional self control to use it maturely, instead of sticking to polite and private one to one conversations they resort to insults and public shaming in group chat, party wide parser's being the tool they use to do pick their target for their anger and hate. Maybe if less people misused it then myself and SE would have a different policy or stance about it.
I have considered that yes. If everyone used it I believe personally it would merely increase the amount of people insulting and being abusive towards others. As shown in here already some people really can't seem to keep their emotions in check and it would be like giving everyone a loaded gun which would increase the amount of people shot. I cannot prove that would happen, it is just a guess but one that makes perfect sense to me.
The thing is even if they are talking to the right person and the person was doing badly...there is still a right way and wrong way to discuss it with them. There is no simple solution since everyone using one could potentially increase the amount of abuse that goes on, personal parser's won't please those who also want party wide ones, people won't all act maturely or more responsibly with it and no matter how strict SE's policies may get on abuse it won't stop some people who lack self control from using it in a bad way...but I cannot see how anyone can pretend that it is not being misused, it is that misuse is a valid reason as to why SE does not officially support.
