Problems of a Lay Mediator Questions:


  Is it normal to shy away from your family when it is hard to interact
  with them because they are so caught up in defilement and shaming my
  practices? 
  
  And is it proper to not respond to other people's questions or
  comments such as "wasn't that so good" or "do you like/dislike that?"
  or even "you believe in God, right, and you're a good Christian,
  right?" I seem to get these questions and have a hard time putting
  together an answer.
The Buddhist practice revolves around 3 practices:


development of morality and ethics with a view to developing control over the mind
development of control over the mind with a view of developing wisdom through direct and empirical experience
developing wisdom through direct and empirical experience


There is no shame in doing any of the above. Regardless of if you are from a particular culture or religious background you can practice them.
