I agree! I think Natasha would most definitely let him have his way on how they view Christmas. From personal experience, one bad memory that surrounds the holiday (even something small and normal and not earth-shaking and cruel like some of his might be) can leave a horrible taste for years and years down the road. Clint had too many bad years to offset anything that Natasha could try to bring to their celebration.

That is not to say that there can't be healing in what the group does. He could enjoy it and be glad that he had participated. Just don't expect him to be first in line for planning it the next year!
