Arguing over the internet is not pointless at all.
Trying to change someone else's mind over the internet (or, indeed, at all) is pointless, yes, but there are more people involved than just those "arguing", and THOSE people are the important ones.
And, truth and facts are always, always of infinitely more value than lies and misinformation, whether by negligence or purpose.
No, it is never, ever pointless to speak the truth in public. If people are going to speculate, at least they ought to do it with their eyes wide open.
If people are dumb enough to purchase items because of something a random person on the internet said and they dont do their own research.
These people have no one to blame but themselves.
So are we now going to argue over how i disagree with what you say ?
Arguing over the internet is 100% pointless.
You will never change my mind and i will never change yours but we can argue till the sun goes down no winners just people with keyboards.
