I would be very happy if people who oppose nuclear would abstain from supporting the fossil fuel industry. When EU voted on green technology, one side voted for nuclear to be defined as green, while the other side voted for natural gas to be given the green status.

Looking at different party platforms here in Sweden (and similar parties in nearby countries), there is a major split between either supporting nuclear or supporting a combination of renewables and fossil fueled power plants (which sometimes goes under the name of reserve energy and other times as thermal power plants). Usually it is combined with some future hope that green hydrogen will replace that natural gas at some time in the distant future.

We could have people with positions that is neither a grid with natural gas nor nuclear, but I have yet to find that in any official party platform. Opposition to the fossil fuel industry should be a stop to building new fossil fueled power plants, and a plan to phase out and decommission existing ones. It is difficult to respect people who claim to believing in a climate crisis but then stand there with a shovel when the next gas peaker plant is being built, then arguing how bad nuclear is to combat the climate crisis.
