Thanks for taking time and updating this, Karthikeyan Singaravelan. I do agree that there there is no proper way to find out if an object is of type socket or not. 

However other fixers in lib2to3 are not any different. For example the fix_dict.py changes every instance of viewkeys() method to keys() irrespective of the type of the object. And I guess that applies to all other fixers in lib2to3 as well. So that convinced me that a fix for this can also be accommodated.

A compromise that we could foster, as I already mentioned is to make this fix explicit so users can use this only if they need it. Please find attached the fixer I wrote. I haven't made a PR yet.
