To me, looks like Mr.Mappillai just likes to Show off.
He is just using Thirukkural as a medium to make noise. It is not his true intention to make people understand or help people to understand the richness of Thirukkural.
If he wants to help people of other language and culture to know more about tamil & its rich literature he should rather do it in a different way. There are lot of sites asking for people to translate tamil literature to english.
So, Mr.Mappillai,
Avoid offending the others. Go to the right place and do it.
You are doing the right thing in the wrong place.
it gives a negetive feeling.
To make it more clear,
Under "Vinai cheyal vahai" athikaaram # 675
"PorulKaruvi Kaalam VinaiYidanodu Ainthum
Irul theera ennichcheyal"
Meaning:
"Before you do something give considerations to
Cost, Worth, Time , How to and Where to"
Thanks
