Are you avoiding all use of fossil fuel while alternatives become available?

It is a bold claim to make but not something that usualy be done. Any abrupt halting of fossil fuel would severely impare the ability to develop and produce alternatives.

We need to transition to sustainable methods. If you want to go cold turkey, go ahead and cease driving an ICE, never travell by air or have anything delivered (and that's just the tip of the iceberg), it would be a counterproductive way to reach sustainability, that is your right, but you can decide to do that to yourself. You don't get to decide how others reach sustainability.

There is a difference between advocating for a better world and acting like a bully because you don't like the current world.
