We all have a duty to read writings in the most charitable light possible. To deliberately misinterpret in the worst light in order to protect oneself from insults or to find evil in others is not charity but pride.
The fact that people are so emotional and subjective online is not because of texting, emailing and posting, but because of bad parenting and lack of self-denial.
Letter writing has existed for all time and is no different in essence, than texting, emailing and posting online.
