Thanks for your post Momo, the more people talk openly about discrimination of any form, as well as racism, bigotry and similar injustices out there, the more I believe it has a positive effect on more and more people realizing that everyone can and should recognize that these things are not the right path to go down, and that they are nothing more than artificial division between people. Look at the great strides that have been made in the last 100 years to combat various forms of discrimination already for the greater good of all mankind and it's clear both that such progress will continue to be made more and more as time goes on and also that it needs to be made.
The more inclusive we are of people, the more tolerant of their different views and different lifestyle choices, culture, etc. the more we all come together on this rock hurtling through space. There are far bigger issues out there that demand our collective attention than tearing each other apart because of the way we look, talk, or personal preferences about how we live our various lives. Hopefully more and more people come to realize this and develop increased tolerance and compassion for others even if they have opposing views.
Very sorry to hear about your dog also, they quickly become like a family member to us and it's always hard to experience their ills and eventual loss. I wish you and your little friend well, hopefully you'll have a lot more time together yet to come!
