I fervently believe in the rights of women, people of color, LGBT people, the disabled, the poor, religious or secular minorities of whatever kind. I am not, however, an ally of any of them.
I realize that no offense is meant when one uses that term. Still...
'Allies' implies - to me at least - a common cause in a tactical sense, not solidarity in a fundamental way. The US and USSR were allies in WWII (Nazi Germany and Imperial Japan were just as much allies of convenience/necessity). Royal France was an ally of the Thirteen Colonies - not because of any higher motives, but because neither wanted Great Britain to win. The list of Cold War allies, on both sides, who fit that pattern is too long to list in even a long diary. NATO has alliance in it's name, and it started life as an alliance, but nowadays you can't get in unless you are a democracy that respects human rights; sure there are other conditions and rightly so, but I digress.
So anyhow...
I am not your ally. One can change allegiances, but nobody can change the fact that I, you, or him, or her are my fellow humans.
We all deserve the right to be free to be who we are and say what we think, the right to be free from fear and persecution, to have food on the table, clean water to drink, a roof over our heads. A right to work for a decent wage, a right to education, a right to contribute and a right to self-realization. All of us.
In Dutch, an ally is a "bondgenoot". I am a "medestander", literally it means I stand with you; add an 's' and it means "we stand together". Google translate says it means "fellow thinker", and although GT sucks at nuances, even that is good enough.
So please find a better word than ally.
