I saw this post today

on one hand I think this is the right thing to do, on the other hand my priest has said to silently pray/bless and do the SOTC. Frankly I am introverted and quite cowardly, I have told two people about their own vain usage/blaspheme before and it seemed to work out well, they said they will try to stop saying it (most don't realise what they are doing).
But
There are always those who hate Christ and will either outright sin the more when rebuked (even if rebuked with love) or sin secretly. In the comment section of this post, most are in agreement with the OP (not surprising as people see the content of those who they follow and usually have the same interests/beliefs) however they are some comments who outright attack Christ and sin the more because of it.
What do you think is the right thing to do? I personally think the OP is right, my priest is wrong, and that those who choose to add sin to sin have themselves to blame. I just wish I could be stronger in this, less my Lord say He is embarrassed/ashamed about me because I was too ashamed/embarrassed/cowardly to publicly stand up for Him.
