Ignoring that part of the party or not even learning about it, what it means or why its there, can actually hurt the causes. Many people drifted democrat, because of the social issues, they don't understand the conservative side except thinking that it wants to make them live a certain way, in college, there were college kids who believes the republicans wanted bigger government to control them and there lives (idiot lefty teachers were big on brainwashing). The social issues are going to be inherently linked with the fiscal side, they need to learn to see how they are linked and why.
I agree with you that it can and it might, but only for some of them. For many of them, I think, becoming a part of the process will expose them to many other conservatives who stress social issues. I've only been interested in politics for a few years, and I feel that talking to other conservatives (and liberals who disagree) has done much to strengthen my beliefs and arguments. Similarly, meeting older conservatives will mold these students in ways neither group can anticipate and they will likely allow the students to bring together social and economic conservatism in a coherent way. Have a little faith in these young conservatives -- they are still in a process of formation.
Fortunately, I think the nature of political discourse is that we all don't have to be big picture people. Some of them might be Stephen Moore types and focus on pro-growth fiscal policy. Others might be pro-life or pro-2nd Amendment activists. Others may advocate a robust defense or for actually enforcing our immigration laws. And others may drift left or drop out of conservative activism altogether. At present I think a net good is being done by this group students at Bucknell and those like them.
Sounds like the next generation is sawing off the social-big-government ball and chain that has limited the appeal of conservative ideas in general.
