Essentially in your mind it isn't fascism until all aspects are 100% accomplished and the nation is under the boot. In reality fascism grows over time in that direction, with a variety of policies that enable fascism, and a series of leaders who either push one or another policy forward or who decline to oppose existing fascist policies. This is an age old debate, but the most common "it's not fascist" line of argument is the one you are making, and it's most commonly made by the far right to claim that since it's not *all* in place we can't call it fascism.
In reality the US has had elements of fascism from it's very founding, and they have never been expunged. Germany learned from us, and we since then have done very little to counter our fascist tendencies. Our 'leftist' leaders are to the right of virtually every major democracy in the world, and leaders like Obama would be considered center right in most of the world.
Again, I like Obama, he was the best president of my lifetime. But he supported explicitly fascist policies around border security and surveillance, and perpetuated war crimes overseas, many of which he personally authorized. It is not wrong to point this out. Being able to admit to this is how we are NOT a cult of personality like the right has become.
