We don't have to define it. That's the point. It's already been done for us.
It's the same with asking me to list reasons or sources that explain the republican parties fascist tendencies, while that's been done thousands of times through the course of their campaign. If you were truly curious as to why people might feel that way, you could have done so at any point during the last few months.
You did't accept the definition you bothered to look up and you didn't accept the valid concerns people had during the campaign.
The real reason you're walking away from this conversation is because you don't care if I am right.
You're not afraid of fascism, because you think you're in the right group.
If you replace nationalism with partisanship, in very many ways the modern left is far more closely aligned with the vile components of fascism than the republican party, or even Trump supporters. The left have done everything they can do vilify anyone who disagrees with their core beliefs, which they hold are a matter of morale superiority and to which, in their minds, no person of moral substance could ever find disagreeable.
By very definition, conservatives are conservative. When they disagree with someone, they continue to treat them respectfully and move on with their lives, comfortable in the reality that there exists people around them with very different beliefs than their own. The left, on the other hand, do no such thing and yet look in the mirror and convince themselves that they're the better people in all this.
Trump less won this election than the democrats did lose it by arrogantly putting up a candidate with strong ties to the current unpopular administration and whose other policies and attributes did not appeal to the swing voter.
And I'm factually correct when I say that Trump’s rhetoric is dangerous. He has motivated even a reasonable person like you to defend him vehemently. He made you part of his group, and by the looks of it you’re already starting to hate those who are not in it.
