This kind of bothsidesing is either hopelessly naive, intellectually lazy or a deliberate attempt to minimize right-wing violence by falsely claiming the "left" is just as bad.
What conservative ideas do we "need" exactly?
there is no compromising with fascism. We are quite literally black-bagging people and unlawfully deporting them and/or putting them in camps, some in our country, some in third-party nations like El Salvador. What's the compromise here? Only black-bag half as many people?
Also, in the US in particular, there is functionally no "left". Everyone is a neoliberal and we have two parties: the center-right Democrats and the far-right Republicans who both defend American imperialism and domestic and foreign capitalist exploitation, who only differ on inconsequential "social" issues.
> In the end we all have a the same goal
No, we don't. The goal of our political establishment is to further concentrate wealth in the hands of the already ultra-wealthy and further impoverish the working class.
You still enjoy a lot of benefits that the left fought for and the right bitterly opposed: weekends, a 40 hour working week, vacations, job safety, Social Security, Medicare and so on. The right wants to literally do away with all of those things.
The core organizing principle of the American right is cruelty. It's exacting revenge on their perceived enemies, be they immigrants, trans people, queer people, women or black and brown people.
