You can't control what others say and do, but you can control how you react to it.

There is no need to defend Poser or your choice for using it.  Their views are elitist and nothing you say will change their opinions because they aren't interested in changing it or seeing it from a different point of view.

Pick your battles :)  This isn't one worth fighting or getting your blood pressure raised over.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
