When someone goes out of their way to cause actual physical harm (think endocrine) via denigration, vilification, and calumny (a libellous statement) at an 'attempt' to completely destroy a warm soul's decent character and self worth in one short vicious sentence using 'S'words not just mere casual words yet continues contact AFTER you have explicitly told them to leave you alone, that is not only sheer arrogance but it is also emotional abuse!
The subsequent unwanted communication has not been read and never will be. Consent is not given to receive contact from this vile sanctimonious bully. It is totally acceptable to have someone not agree with you or even to be proven wrong, that is absolutely fine, just don't be so unpleasant by treating others as though they are completely worthless with defamatory words based on sheer ignorance!
The guard was down by getting involved in a subject that is of genuine interest. As a result a kind nature (with basic neuro/adrenal defences already down) was with malicious intent exploited. Do NOT mistake kindness for weakness! This had an immense negative affect for some days. Now moving forwards, however this needs to be put out into the universe to try and make others stop and think of the consequences that can result from treating others like complete utter fucking garbage. Another life lesson with great gratitude is learned, so thank you for the favour! 😉
