The terrorist attacks on Sept. 11 changed many things in the United States, including, perhaps, the way the public looks at what university faculty members are saying.
A group of Vietnam veterans see similarities between some things being said on college campuses throughout the country now and what was being said on them during the Vietnam War.
"There's been quite a bit of controversy about what the professors are saying," said Leonard Magruder, founder and president of Vietnam Veterans for Academic Reform.
Although Magruder did not serve in the Vietnam War, he was a professor of psychology at Suffolk College in New York at the time of the conflict.
He said that as a professor, he witnessed how some educators told their students the war in Vietnam was America's fault.
"I watched this happen from that point of view," he said.
Now, Magruder believes that there are similar situations going on at several other campuses throughout the country.
At the University of New Mexico, for example, a history professor was asked to resign after he made a remark during one of his classes on Sept. 11.
The professor said that anyone who could bomb the Pentagon would get his vote.
So far, Penn State has avoided controversy.
University spokesman Tysen Kendig said that there have not been any issues that he knows of involving any professors' comments about Sept. 11.
"If there have been, it has not been anything of significance," Kendig said.
Anthony G. Roeber, history department head, said that although he had heard of some professors at universities across the country gaining attention for their unpopular views about the attacks, he said that does not appear to be the case here at Penn State.
Roeber said that he hasn't heard of any student complaints about professors giving their opinions on the subjects.
In addition to remarks that have been made by professors, the veterans' group is also concerned about the fading patriotism that they say has come as a result of time distancing the attacks from the forefront of people's minds.
"They are a little upset with the way that patriotism is slowly deteriorating," said Karen Charchan, president of the Penn State University Veteran's Organization.
Charchan said that membership in the PSUVO is not limited only to members of the military who have served in a war, but also to anyone who supports veterans.
Charchan said one of the members of the organization was upset, as a student and as a veteran, by the lack of concern on the part of some professors at Penn State on the day of the attacks.
She said that he was troubled by the fact that even while the attacks were happening in New York and Washington, D.C., some professors were still having class and still going over material in their classes was to be testable in the future.
While Magruder said that he believed that the climate on college campuses was more negative toward the military during the Vietnam War than it is now, he still thinks it is important to react to the most recent issues.
"We thought we would address it right away," he said.
