I am not in any way saying that you can’t express your opinion. But similarly you can’t express an opinion and expect it to stand their unquestioned.
The whole point of the discourse is to engage in discussion and work through problems/ issues constructively.
You expressed your opinion, and I replied with my take on it all. There needs to be a consideration of both sides. It is obviously easy to come in and say “this is wrong because of this” or “I disagree with this”, the test comes when your opinion is reasoned, questioned, other points of view are introduced, and you reassess your thoughts based upon everything you have been told.
As @voxel_pirate has said, we need all sorts of people and constructive criticism is a must have.
