I'm not one to say anything in regards to proper grammar and writing skills, I admit that I wasn't the most studious pupil in my younger days. I do regret that now.
However, I do understand that proper communication skills are very important in a good cultural society. Of what use is the highest faculty of our being, our minds, if we are not able to express it properly and with clarity?
As G. K. Chesterton said, "You can tell a Catholic by the way he climbs a tree." In other words, everything should be done well and with purpose. We shouldn't slide into bad habits just because it may be the norm of the day.
