It's... complicated. Like you said, the Russian interference and assistance to Trump is real and impactful. I don't think it should at all be ignored and everyone, including the president, needs to be removed and held accountable or it will keep happening and get worse.
But you have bad faith actors on both sides of the debate here.
You have people trying to downplay the effects of interference to boost their own agenda, whether that be pro-Trump, anti-democrat, or the weird/misguided lefties who reflexively defend anyone opposed to the West (and are skeptical of US security state for good reason) and for some reason still try to defend Russia even though it's a crony capitalist kleptocracy now.
On the other side, you have the more establishment Democrats and liberals who overplay the issue, or rather try to pin all blame on that instead of reflecting on their own failures. The DLC, Clintonian consensus in the party had utterly failed and is crumbling for reasons that have nothing to do with Russia, but party leadership doesn't want to change or piss off donors by embracing the shift in the left. So they bury their heads in the sand and deflect everything to Russia in the hopes they can go back the old status quo, which is in fact now dead.
