Are you still too afraid to vote for a third party?

I made a post a while ago about voting third party and many said that they thought it would cause the democrats to lose and essentially our democracy would be downgraded. I think that's always possible, but right now Biden's second term is more likely than not, and it may be worth the risk given that neither party will ever make the changes I want. A third party is very unlikely to win, but could force democrats to agree to policies before handing over its votes. What are your thoughts?
