What do you think? What do you have to tell about these people?

Sometimes, Facebook come up with a trend and almost everyone follows it to the point it gets overrated and someone has to point it out how lame it has become. However, people like that someone also criticise everything you do on Facebook. I mean everything is uncool and mainstream for them. Yesterday, I have shared some of my friends’ birthday greetings on messenger day because it was really hilarious and of course, they approved of it. The next day I saw someone criticising me indirectly by saying how lame it was of me to upload such things on my messenger day. I mean it is my Facebook and you don’t tell me what to do or not! The reason I shared this here because I want to know how will I respond to that.
