Others
If your faith is so weak it can be threatened by another person's beliefs...
If your marriage is so shaky it can be threatened by another person's relationship...
If your sexuality is so uncertain it can be threatened by another person's desires...
If your gender identity is so immature it can be threatened by another person's quest for equality...
If your concept of unity is so skewed it can be threatened by another person's skin color...
If your patriotism is so fragile it can be threatened by another person's language or nationality...
If your wealth is so defining it can be threatened by the needs of others...
... The problem isn't with those 'others.'
