I disagree.
If you can't use proper English, why am I supposed to take you (general sense, not you, Frank Underwood) seriously or offer your argument a single shred of credibility?
I mean, the stuff I mentioned is not and never was difficult to grasp, so constantly messing it up tells me that person is a moron not to be taken seriously.
I agree to an extent as well , but somebody misspelling “too” or “to” on a message board doesn’t really strike me as something to get super upset about and automatically label them an idiot or “not worthy of my time.”
Often times, I’m typing so fast on my phone as I’m walking around or whatever ... that mistakes/ typos occur. Perhaps it’s the same for others ?
