Fair comment. Remainers need to spend more time explaining how countries in the EU will benefit from membership over the next 20 to 40 years and why the UK should be one of them. Leavers say negative things about the EU of course, but they also seem better at putting a positive spin on leaving, 'control', saving contributions, new trade deals and so on.
I feel fingers twitching at keyboards about to tell me the Leavers are wrong, which is kind of the point, we need to hear more about why the EU is a good thing.
